is over and season four hasn't begun. So what is this episode? This is an episode I've been meaning to do for a long time, a crypto 101 for all the newbies who are curious about this space, but don't know all the lingo yet. So if you're a seasoned crypto person who is tired of answering questions for your friends and family about the space, this is another great episode to share in addition to the one earlier this fall, how to explain cryptocurrencies and blockchains to the average person. Here to turn the tables on me and ask me questions for this episode is Elaine Zelby, who's been helping me with Unchain these last few months. Hi, Elaine. Hi, Laura, and thanks for having me on. Oh, well, thanks for asking me questions.

So I'm really excited you're doing this episode because I do feel like there are so few resources out there to really onboard people into the world of crypto. So let's start at the very beginning. What is Bitcoin? So Bitcoin is a number of different things. We can think of it as digital gold. It also functions as digital cash. But the main distinction that I guess it has now is that it's the first cryptocurrency. Bitcoin is also the first decentralized currency that's not issued by a central government. It exists outside the traditional banking system, which is pretty unusual because so far for most of us, for all of us, in fact, for all of our lives, the money that we've normally dealt with has been issued by a central bank. And this is the first time that we're really seeing money in the form

of software. And the other reason that Bitcoin is unusual and and novel is that it's really the first scarce digital resource we have. And by that, what I mean is that previously, if we were sending things on the internet, those were typically copies of things. So for instance, if I sent you an MP3, or if I sent you a text message or a photo, I would also have a copy of that MP3, that text message or that photo. And so Bitcoin was the first time that you could send something you could send something digital to someone.

And once I sent it to you, everybody in the world would know for certain that I no longer had it and that you know, had it. And as we've seen, Bitcoin has really ushered in kind of a new era, I guess you could say for the internet, where now blockchains are enabling these new digitally scarce objects to exist that, you know, weren't possible before. And people are calling it sort of like a trust layer for the internet because you can trust that something hasn't been counterfeited in a way that you couldn't before. And in that respect, because blockchains will usher in all kinds of new and novel products really on the internet that we that were simply not possible before, in a

way, Bitcoin is actually the first application for Blockchains the same way that email was the first application for the internet And I think the other thing that I like to think about when it comes to Bitcoin is that it really is a new form of money that is actually also it also represents progress in the types of money that we've had before so if before we had seashells and tally sticks and yapstones and then gold and more recently paper money. Now we have digital money that is more fungible, easily divisible, more transportable. And so one of the CEOs in the space who's pretty well known once as Casares, the

CEO of Zappo, I know that he's called it the best form of money we've ever had. And I actually, I would say that I agree with him. Although one thing I would add is that since it's so early in the days of cryptocurrency, it's hard to know really which of the many different currencies we're seeing will be winners. So whether or not Bitcoin retains its first mover advantage here, it's too early to tell. So you mentioned that Bitcoin's the first form of digital money, but when I think about the banking system, isn't it digital already? I mean, I bank online, my credit card is online. I don't really hold cash. No.

So actually the... the interface that you are dealing with is just a digital veneer on a centuries-old system called double-entry bookkeeping. And in that system, both of the parties that are transacting keep their own ledgers and then reconcile them. And within that system also, there are many middlemen. So for instance, if you try to send an international wire transfer, and let's say, you know, let's say it's you're sending one to me and you are in Senegal and I'm in Costa Rica. most likely that's not a very common corridor for people to send international wire transfers through. And so most likely your local bank and my local bank do not have

a direct connection. And so that kind of transaction would actually be passed along through a number of banks, including what's called correspondent banks. And it's sort of act as hubs, similar to the way that certain airports are hubs that connect then less well-trafficked cities. And so, Here, you know, with Bitcoin, you're actually using the software to make the transfer. And so let's say again, like you're in Senegal and I'm in Costa Rica, you and I can just take out our phones and you can send me some money, you know, Bitcoin or another cryptocurrency from your phone and I can receive it in Costa Rica as well. And that can happen near instantaneously. Whereas international wire transfer, for those of you who have experience

with them, can take a frustratingly long time, maybe like a week or even more, and they can even get lost. And this has actually happened to me. And so with cryptocurrencies, what's really interesting about them is that since all the transactions are recorded on what's called a blockchain, which is usually a public ledger of all the transactions, the parties that are transacting can actually see where that transaction is. and track it. And depending on which blockchain you're using, the money can be moved in, for instance, within 10 minutes, if you're using Bitcoin or any of the coins that are modeled after Bitcoin, such as Bitcoin cash, or they can move even more quickly, such as with Litecoin, which is using what are called block times of two and a half

minutes. And a block time is basically how long it takes for a transaction to pass from one person to another. And the Ethereum network has an even faster block time of around 15 seconds. So this is truly digital. And the reason for that is because the assets themselves are actually digital. And the other thing that's kind of an advance on the traditional banking system is that when you're dealing with cryptocurrencies, the fees are known upfront. Whereas if you do an international wire transfer, you will only find out how much you've paid in fees once the recipient finally receives the money and sees how much has been taken out. And again, I've been on the receiving end of this and have been very frustrated by not knowing how

much to charge basically so that the other person pays the fees. So this is, I think, a vastly superior system to the traditional banking system. And when I say that, that would apply even to things like PayPal, which seem digital as well, really are not because they run on the traditional banking system rails. Okay, great. So we have the first truly digital currency and you talked a lot about how it moves around. So I wanna dive into that a little bit. When you were mentioning Bitcoin originally, you talked about blockchain and these two are talked about typically in tandem. So can you walk us through what is a blockchain? So you can think of a blockchain as a big ledger in the sky almost. It's a ledger that essentially exists in the cloud. And this ledger holds the history of every single

transaction since the beginning of the network. So if you look at the Bitcoin blockchain and go all the way back, you will find the very first transactions that happened in January of 2009. And you will see every transaction since then. The other interesting thing about this ledger is that copies of it are held on computers worldwide. So this makes it actually quite difficult to change the transactions in the ledger because In order to do that, you would need to gain control over a huge number of computers to change the version of the ledger that they're all holding and to kind of change the agreed upon truth that all of these computers are running. And this is why often people say that blockchains are tamper-proof and transactions

cannot really be reversed. The only way that you can really reverse a Bitcoin transaction is if, so let's say I send you a Bitcoin, The only way to reverse it is not the way that we would typically do with a credit card where you get a charge back and it's like the transaction never happened. The only way that I would ever get those Bitcoins back from you or have the transactions reversed is if you actually sent the money back to me, which is essentially just another transaction. It's not undoing the previous one. So in terms of where this term blockchain came from, a blockchain, is called a blockchain because all the transactions are grouped together in blocks. And a block happens in Bitcoin at least every 10 minutes. And

as I discussed earlier on different blockchains, the block time is sometimes shorter. So one block is processed every 10 minutes and each block is linked to the one before it. And that's why we call it a blockchain because it's essentially a chain of these blocks that contain the most recent transactions. And within each block, you've got, you know, all this data, right? Like all all of these transactions that have happened in the last 10 minutes. And in order to give each block a unique identifier, you do what's called you run a hash on it, which is you put it through this algorithm that then creates a unique identifier. And if you were to change one tiny data point in that group of transactions,

then the hash you would you would get is going to be is going to be wildly different. And so even if you change like a decimal point, or just a single digit, you would just end up with a completely different hash. And the way that you link all these different blocks together is that each block actually contains the hash of the previous block, which as I said before, is a data point where if you changed any part of it, then that would cause that block to have a wildly different hash. So that's why even if somebody were to gain control of a whole number of these computers that are running the Bitcoin software to try to change the history of the ledger, they would have a really hard time changing anything more than kind of the most recent transactions because you would kind

of need to undo each block. You know, it's not something where you can just kind of like undo the whole thing all at once because each block contains data from the block before it and so that's why everybody always says like this is quite secure and it's very difficult to counterfeit yeah so that's that's how blockchain works awesome so blockchain's storing the records of all this movement of bitcoin but how are the bitcoins created in the first place how do we get them in existence and how many are there so the bitcoins are created through this process called mining and they are essentially released by the software with each new block. And at the time that Bitcoin was first launched, the software was releasing 50 new Bitcoins with every

block. And then every four years now, the Bitcoin software undergoes what's called a halving event, where that figure of the block reward, which is the number of Bitcoins that are released in any given block, gets halved. And so after four years, the software began releasing the 25 Bitcoins. And then in the summer of 2016, we had a number, another halving event. And so now the number of Bitcoins being released every 10 minutes is 12.5 Bitcoins. And the people who get those new Bitcoins are what are called miners in the Bitcoin network. And these people are essentially the people or the entities, because

actually a lot of these people are, or a lot of these entities are now corporations. But they are essentially securing the network you can you can say or they're, you know, running the network. And the reason that the block reward exists is to incentivize them to run the network. And what's really interesting is that the more computer power you put on the network, the more likely it is you'll win more Bitcoins. Like over time, the amount you'll win is sort of proportional to the amount of computer power that you have on the network. And at the same time, the amount of computer power on the network is also what keeps it secure, right?

Because the more computer power that is on the network, the more difficult it is to attack the network. And so it's a pretty neat kind of circular mechanism by which you, the, or the software is, is being kept secure. You know, you incentivize these people to try to win the Bitcoins, but when they do so, they're, protecting the software and keeping it from being vulnerable to attack. One other thing that I want to add here is that what determines whether or not a particular miner wins those Bitcoins is there's kind of like basically a math problem that happens with each new block. And so the computers on the network are all racing to try to solve that first and whoever solves it first will win the Bitcoin. And Anyone

who wanted to attack the network would need to amass at least 51% of the computer power on the network. And that would enable them to win the competition at least 51% of the time, which would perhaps give them the power to change the ledger. But as I mentioned earlier, that would really only give them the power to change probably maybe the most recent block, depending on how much power they had, perhaps the block before it, but it would be pretty limited in terms of what they could do. That sounds like a very interesting alignment of incentive there, I thought through. Let's move on from Bitcoin and talk about another major concept in this space, which is Ethereum. Can you break that down for us and tell us what is Ethereum and how does it work? So if Bitcoin introduced this concept of using technology to

send money directly from one person to another, rather than going through a bank, Ethereum goes a step further. It brings us this concept of using software to replace middlemen for all kinds of services. And the way they do that is by providing this platform for what are called smart contracts. And that's essentially software that is like programmable money. So one of the examples, and this is a pretty simple one, is you can think of using Ethereum to, for instance, send your child, let's say maybe they're in college or something, to send them maybe it's like 10 ether every time their account balance falls below five ether or

something like that. And it's not something that you would have to manage. And it's not like I said earlier, something that's just a digital veneer on actually the traditional banking system. This would be something done through your phone. And And actually I wanted to just draw the contrast with Venmo, which many people perceive as being done through the phone as well. But Venmo is just moving money from your bank account to another person's bank account. So again, that's different. This is using a natively digital asset and moving the money to peer to peer. So some other more complex examples of things that you could do with a platform like Ethereum are you imagine using a smart contract for

escrow services. So let's say that you're in the process of purchasing a house. Typically, there's a trusted third party that you use to hold the money while you make sure that you can obtain the deed. And then that person will facilitate that transaction and be the trusted third party so that the buyer and the seller don't have to worry like, what if I hand over the money and don't get the deed? Or what if I hand over the deed and don't get the money? And here you could actually use the software to instead facilitate that transaction and be the trust layer between the two people. So the middleman is not needed. And the more that this gets built out, the more infrastructure that

we have in place, you could eventually see someday software replacing all kinds of middlemen for services that are widely used today. So for instance, you could imagine a sort of eBay without an eBay at the center, just a huge decentralized network of buyers and sellers that are using this trust layer, like I said, on the internet to directly interact with each other. And instead of having this middleman at the center take a cut of every transaction, people are just dealing directly with each other. You could also imagine that such smart contracts could be used in combination with the Internet of Things to, for instance, power a taxi fleet, such as

an Uber that can bring you a car on demand and you can pay it automatically and not have this third party either facilitate that transaction or take a cut of it. And so there's a lot of interesting things that are being built on Ethereum in that fashion, including some peer-to-peer trading we're already seeing recently in something called CryptoKitties, which sort of combines a couple of really new and interesting things that have only been possible now with blockchain technology, which are to have digital collectibles because of what I mentioned earlier about how now with a blockchain, you can create a unique blockchain digital item that cannot be

copied. And at the same time, people are very easily trading them because now you have ether in which people can transact peer to peer.

I'm speaking with Elaine Zelby, who is asking me questions for our special Crypto 101 episode. Okay, Laura, let's get into some really interesting topics. First, I want to go into ICOs. Now, what is an ICO? An ICO is an initial coin offering. And the best way to think about that is to imagine that a Kickstarter and Bitcoin had a baby. So essentially, this is a crowdsale where instead of the product you receive being a sweatshirt or a pebble watch or a video game, what you get instead is cryptocurrency or a crypto token. And the reason that these have really taken off in 2017 is that they offer a number of things to both sides of the transaction that were not

really possible before. So from the entrepreneur side, an ICO or a token sale is a way to raise money without having to go through the process of going to venture capital investors in Silicon Valley who most likely are not going to be super interested in your product and maybe going through the humiliating process of a whole bunch of different presentations and then at the end, not really getting a lot of money. The other reason that I think a lot of entrepreneurs are interested in this is because this is also a way to seed a network, which is kind of a difficult thing to do typically for an entrepreneur.

If you imagine that you're creating, you know, the new Facebook or the Twitter or, you know, whatever it is, when you first start it, whoever joins at that moment, they're not going to get a lot out of it if there aren't that many people on it. And so what these entrepreneurs often are trying to do is if they have a token sale, then they can get a lot of people who are interested very early on and they will draw them in by the promise of, saying, hey, if you participate early, then if this network takes off, then the value of your token will grow. And on top of that, then now, once they've sold the tokens to this early investor base, they have these really energized users from the get-go who want to proselytize the network to their friends and family,

get more people on it. So they have a natural mechanism for kind of incentivizing their own users to grow the platform and basically ensure its success. And so this is something that's been appealing to the entrepreneurs. And from the investor side, I think the reason this phenomenon has taken off is because in recent years, we've seen that a lot of companies have been staying private longer. Typically, when they go public, it's long after the value of the company has already gone up. And so that value now is really accruing primarily to the venture capitalists and the early investors. And so when now with this sort of

democratizing force of these initial coin offerings, people are saying, hey, like I can get in early and I can participate in the returns that typically were reserved for these wealthier more privileged elite investors. And I think the other reason that people are interested in this, frankly, is that I've noticed in general that the crypto space has caused a lot of the followers to be somewhat religious almost about the space. And they tend to be highly engaged. And part of it might be the financial incentive.

But I've definitely noticed that the people who get into this space, they tend to have pretty strong beliefs about which coins are good and which ones are not. And, and they really want to see their coin succeed. And I think part of that is because they've essentially put their money where their mouth is. And so, so yeah, so we've definitely seen this phenomenon take off really quickly. And I think there's reasons on both sides for that to have happened. It's been a relief. fascinating phenomenon to watch too, because once you get people to have skin in the game, it's kind of like fantasy football where you're rooting for the team is based on where you've put your bets. And I've seen people do this and become the amplification, getting so many people involved and everyone's constantly watching the

coins on the exchanges and the other market watch sites. The one thing I've seen on these sites too is not only are they listing all of the coins and tokens created from ICOs, but you also get things like multiple Bitcoin coins. So you have Bitcoin and Bitcoin Cash and Bitcoin Gold. How did that happen? So this is what I meant earlier about people being religious. It's kind of interesting. People have very, very, very strong opinions about the direction that these open source networks should go, which actually in a way I think is really important. cool to actually, now that I really think about it. You know, if you are a user of Facebook, you're not sitting around thinking, I mean, well, okay, that's not true. You are probably

sitting around thinking like they shouldn't have done that, or they should do this. But here in this situation where these projects are open source, people actually have the opportunity to put into effect what they want to see. And so When the developer when when some members of the community or some developers disagree with the way that the developers of any particular coin are taking that coin, sometimes what they will do is they will quote unquote fork that code, which means they basically take the code base. and they replicate it, but then tweak it to their liking. So maybe there are some parameters that they would prefer to have different. And we've seen this not only with Bitcoin, but also with Ethereum. And what happens, depending on how you do the

fork, you can perform it in such a way where at the time of the fork, anybody who holds coins on the original chain, so with Bitcoin versus Bitcoin Cash, on August 1, which is when Bitcoin Cash forked off, anybody who held coins on the Bitcoin blockchain at that moment, they also now suddenly had the same number of coins on the Bitcoin Cash blockchain. And the reason is that the Bitcoin Cash developers kept the ledger, basically. So the same ledger of all the Bitcoin transactions going back to January 2009 is being used for Bitcoin Cash up until August 1, at which point that is where the ledger starts to differ. And so that's how... they actually also get a wide distribution for their

new coin because now everybody who has the original cryptocurrency, which has probably the most users out of any of the other cryptocurrencies, now suddenly they have the same number of users. Granted, that number probably changes very quickly because a lot of the Bitcoin holders were super angry about the Bitcoin cash hard fork. And so I believe many of them sold right from the get-go. So obviously the number, the histories of the two blockchain changed pretty much immediately. But that is why you end up with these different quote unquote forks. And we also saw the same thing happen with Ethereum where Ethereum started out and then there was a sort of mistake, I guess you could say, where essentially there was a smart contract that was

on the Ethereum platform called the DAO. This is a very long story, so I'm not going to go into all the details, but that smart contract had a bug in the code that enabled a thief to steal, I think it was like about $50 million worth of Ether at that time. And this happened when Ethereum itself, the network was not even a year old and the community and a lot of people had put money into the smart contract. It had raised $150 million. It was essentially kind of like a venture fund, a smart contract acting as a venture fund. And some people had put in like their life savings and I mean, it was just ridiculous. And so what the Ethereum community decided to do was kind of like roll back, meaning take the ledger back, pretend like this never happened,

and essentially erase the theft. But some people who really believe in that immutability aspect of blockchains vehemently disagreed with this decision. And so at the time of the fork, they bought the quote unquote original coins. And what I mean by that is so Ethereum, what's called Ethereum now is actually the version that was hard forked. It was the version that, you know, moved off from the original chain. And there are some people who kept going with the original chain. Now they call themselves Ethereum Classic. And they have a different coin.

And the one that is called Ethereum is the one that forked off to erase the theft from the DAO. Oh man, this is so fascinating. So much drama and I'm sure that will continue. So much drama, yes. One of the other things I know people tend to get semi-religious about is the way that they choose to secure the networks or come to consensus. And two of the main ones that I've heard about are proof of work and proof of stake. Can you explain the difference? Yeah. So proof of work is what is used in Bitcoin and proof of stake is what the Ethereum community is probably going to move to at some point in the near future. And what you can, the way that you can think of these different mechanisms is there's sort of like ways of securing the network. So with proof

of work, the way that that is securing the network is that requires the computers on the network to put in work to validate transactions. So earlier when I spoke about, you know, kind of like this competition in the math problem, you know, you need to put in work with your computer in order to figure out the solution to that math problem. And that in and of itself, as I explained earlier, is that's what's securing the blockchain, right? Because if some nefarious actor wants to do something to the blockchain, they also have to put in work. And in fact, they have to put in more work than the good actors in order to, you know, do whatever it is that they want to do. And so as you can see, this sort of leads to this like arms race, right? Because you're trying to get better

equipment, faster equipment, put on more mining equipment onto the network. And so it's pretty energy intensive. And what some of the proof of stake coins are doing and what Ethereum intends to do is to switch to a method that is less energy intensive. And what's interesting about this is that it also sort of like switches the vector of attack. So instead of needing to amass a large amount of computer pound their network, what you need to do is mass a large amount of coins. And in the Ethereum proof of stake system, the entities who will be adding new blocks are they will be called validators instead of miners and um the frequency with which they will add new blocks is determined by the proportion of coins they they've put

up as stake or that they've sort of like bonded to the system and that sort of represents kind of like a certain level of commitment um to the ethereum system and so if you think about trying to attack in this environment instead of trying to put a whole bunch of computer power in the network. Instead, you would need to amass a huge amount of coins, like 51% of the coins. And what's interesting there is, again, crypto economics come into play to also help protect the network. Because if you're going to amass all those coins to quote, unquote, attack the network, then the second that you do it, the value of the coins that you've just amassed will drop. And so your financial incentive to attack the network is then gone.

And you've just wasted that money. Interesting. Let's shift gears a bit and talk about exchanges. So I've seen a ton of exchanges popping up all over. How do they work and why do I see some coins listed on certain exchanges and not others and some don't contain the entire list of altcoins and tokens? So exchanges are more like what we're familiar with from the traditional financial system in that they are centralized entities. They are not you know, doing peer to peer transactions. They are not conducting transactions on the blockchains. They can interact with blockchains.

So for instance, if you buy some Bitcoin on Coinbase and you want to move it to your own personal wallet, then at that point, Coinbase will interact with the Bitcoin blockchain so that, you know, your coins will end up back on the blockchain in your control. You will then manage your own private keys. But typically on an exchange, let's say that both you and I are users of Coinbase, what will happen is that Coinbase will use its own internal ledgers to conduct the transactions. And so for instance, right now, there's pretty high fees on the Bitcoin network. And so if you and I are both users of Coinbase, then we can actually avoid those fees if we just send money to each other through Coinbase itself. Now, the reason that

the exchange is different in terms of what they offer for coins a lot of it probably is due to regulatory issues and this is actually something i haven't really discussed at length with the exchanges themselves so i'm just kind of extrapolating from what i know about the space but because they are domiciled in different jurisdictions they probably have different regulations that apply to them Some of them have also, even if they are domiciled in the same place, they have chosen different regulatory routes to be compliant. So there are different licenses you can get or different, just sort of different paths to be compliant. And so depending on which way you've gone, you might need to follow one certain set of regulations that would cause you to list some

coins versus others. And the other thing that I would say here is that, in general, I think, because it is sort of a wild west right now, but as the space is taking off, everyone is quite aware that regulation is coming. I think a lot of these exchanges do carefully look at regulations to understand what could get them in trouble basically. And for those maybe that weren't so careful about it, they now are being much more careful because the SEC finally last summer did, come out with a report that began to kind of draw the lines around what would constitute or what kind of token would be considered a security and therefore would require an

exchange to register with the SEC. And so we have actually seen one exchange come out with a really comprehensive framework for kind of outlining basically how they would think about whether or not to list a new token. And that was GDAX, the Global Digital Asset Exchange, which is part of Coinbase. And if you look at that framework, it's actually really comprehensive. And in my opinion, actually just a really smart way to think about tokens in general, not just for the purposes of an exchange. But they look at factors such as the strength of the team, the governance structure of the coin, the security of the code itself, how centralized this token is, you know, like meaning the distribution of it, the

liquidity, the demand from users. I mean, there's all kinds of factors. It was actually pretty long and thorough document. So I think now we are seeing a lot of exchanges be really thoughtful about it after the Dow report came out from the SEC, we did see some exchanges de-list certain tokens. And the SEC in that report sort of gave a little bit of a warning because essentially they said, you know, anybody who had listed the DAO tokens would have, you know, been in violation of securities laws because they would have been listing an unregistered security. And so I think people are on notice and they're pretty aware and cautious now about what they list. So coming back to this being kind

of the Wild West world we're in right now, let's take a different definition of security and talk about actual security of all of this money and assets being transferred. In my mind, one of the main concepts behind everything running on blockchain technology is trying to solve for security. But we keep hearing over and over again in the news about hacks. So why does that keep happening and is this really secure? So the reason that this is happening is because this is really a new form of money. it's not the kind of money that people are used to dealing with. And for that reason, there are a whole new set of security processes that people need to learn in order to handle this money safely.

And it really is kind of the polar opposite of the traditional banking system, as I mentioned earlier, where you can't, if you lose your private keys, there's no bank to call to be like, hey, I forgot my password, I'm gonna create a new password. That does not happen, right? And on top of that, people are often buying this stuff without really even understanding how it works. And so this is just a new system where essentially anytime you have a Bitcoin, you kind of get like two things with it. You get what's known as a public address, which you can think of as sort of like a mailbox where anybody can put bitcoins into your mailbox now. And the other thing that you get is private keys

to that address. And that is what enables you to send money out of that address. And the only thing that makes it pop that, you know, enables anybody to send money out of that address is possession of those private keys. So if you lose those private keys, and they're just gone, like, not that anybody's stolen them from you, but like, you just lost them, like, maybe that got burned up in a fire or something then nobody will be able to send out the money from that address similarly if you if the money sorry if the private keys are stolen from you then whoever has possession of those private keys they can now send money out of that address and most likely what they will do is send that money into their address and so there's a lot of infrastructure that needs to be built really to enable people to handle this in a secure way And it's simply not

been built yet, really. What a lot of people are doing now is actually just trying to manage their private keys in a way that sort of divorces it from what has made cryptocurrency really interesting so far, which is the fact that it's digital. And so what a lot of people do is they actually store their private keys on paper or on devices that are not connected to the internet. That is called air gapping. Exactly. And so if you have a quote unquote air gapped device, which is something that's never touched the internet, that is a way to protect yourself from having somebody steal them. And yet then you have this problem of having this physical device that somebody

can physically steal. So then you've got people that are dividing up the string of letters and numbers that make up their private keys amongst different devices and then storing all those in different geographic locations. You've also got people who then in a very ironic twist are storing their private keys in safety deposit boxes at banks. And with all the difficulty of kind of managing physical possessions that hold large amounts of money, you have a lot of tales of people who lose huge amounts of money because they toss out the piece of paper holding their private key or they toss out the hard drive, storing their private keys.

And so in the news, you might've seen there was a guy who lost a bunch of Bitcoins on a hard drive that he accidentally tossed out a number of years ago. And just recently, because the price has gone up so much, he actually was trying to get permission to go through this huge dumps landfill to try to find it. And so, you know, it's early days, like a lot of infrastructure has been built out, there are some new ways that people have been, or companies have been implementing to help people secure their keys, such as things like multi sig transactions, which are where in order to facilitate, or in order to initiate a transaction, you need, for instance, two of three signatures or three of five.

And that, you know, is actually quite a good way. Because the other thing about that is that then that protects any single individual. You may have also heard in the news, there was somebody who was held at gunpoint to hand over $1.8 million worth of ether. And so if you do something like a multi-sig, then, you know, you can't actually physically threaten somebody because then you would need to to get everybody who's on that multi-sig transaction to be physically threatened in order to actually get the money. And then the other thing that I think that's happening a lot is that people are buying without really knowing what they're buying. And that makes it very, very easy for them to be phished. And what I mean by that is, you know,

they're sent some kind of link and they click on the link and give away their private key is not realizing what they've done. And often there, what we see is that the fishers are super smart and they send messages that are like very well disguised. You know, it's like, hey, we're the team from X project and we're doing a second sale, but it's only for the next hour. Buy right now. And like people are like, oh, oh, you know, I want to get in right now. And they give away their private keys. And so often, yeah, what they do is they like create some sense of urgency that makes people forget all the security lessons that they might've learned. Because I've spoken with people who've said, oh, I'm so embarrassed because I know what you're supposed to do, but my greed got the

best of me and I forgot and I just clicked and, you know, put in my private keys because I wanted to get these tokens. So yeah, so unfortunately that's, A lot of that's going on. The craziest is the stories have become so mainstream now that even my mom called me and started asking if I had heard about the guy who's going through the dumpsters trying to find this old computer that has millions of dollars worth of Bitcoin. And my mom knows nothing about this. So it's just a crazy time right now. Yeah, and actually, there was one thing I wanted to add that I forgot about, which is I'd written a big story last year. And I've spoken about this before in the podcast. So hopefully my listeners are aware about it. But the other thing is that our phone carriers are not aware of how important our phone can be to our financial security. And so

Sometimes what the hackers are doing is, let's say that you are on Sprint. They'll call up T-Mobile and they'll be like, hey, T-Mobile, I'm Elaine. I want to move my phone over to T-Mobile. T-Mobile will call Sprint. They'll move your number over now to, let's say I'm your hacker. They'll move your number over to my phone. And then I go to like Coinbase and I type in your email address and click forgot password. And then it sends a code to my phone and then I can change your password. I can move your Bitcoins. I can do whatever I want with your money. I can get into your email this way. I can get into your Twitter. There's just so many things that these hackers can do with your phone number, which is why a lot of people in the crypto space, and if you

are new to the crypto space, this is something you should be very aware of. any, literally these hackers will go after even just like a few thousand dollars. If they see anybody tweeting about owning Bitcoin, they will target that person. And we saw this with, there was a medium post that went viral. This person lost $8,000 worth of Bitcoin. And in my story, I wrote about somebody who lost millions of dollars worth of Bitcoin and they will go after whatever it is that they can find because obviously the value of these cryptocurrencies is going up. So even if it's a small amount at the time, it could be a greater amount later on. And the phone companies, frankly, when I was reporting that story, it was very obvious they had

totally ignored all the complaints they've gotten about this. And it was only when I started digging around that they seem to actually care and start helping these people. And, you know, I haven't seen much... improvement in that record, unfortunately, because there are still people who are being targeted this way and losing money this way. So if you are new to the crypto space, I would counsel you to not do what's called two factor authentication through your phone number, it should be to a device to an application such as Google Authenticator or a YubiKey, which is kind of like a physical device that can authenticate you. And essentially, basically just do not tie your security, especially for your email, your crypto accounts and any

financial accounts or any other accounts that contain sensitive information such as Dropbox, Evernote or anything like that, you know, your iCloud, do not connect the security of those to your phone number. That's terrifying, especially when you think about the fact that even a highly educated person who follows, you know, typically relatively good security protocols could easily be subject to attack with that. Oh yeah. Yeah. There were a lot of very high profile people who were extremely successful in life who lost a lot of money that way. Um, you know, because yeah, the phone companies, they, they, they are not aware of, um, the fact that your phone number is now used to secure most of your digital life or if they are

aware they, they don't, make it a priority to protect it. I want to go back to one of your previous points on the fact that most people right now don't really know what they're getting into and don't really know what they're buying. So I have to ask the question that I know is in most people's heads right now. And is this all a bubble? So I wouldn't say the whole thing is a bubble. Obviously the technology is, it represents some kind of breakthrough. And I do think that some, new progress and a lot of new advances in technology and new cool products and applications will emerge from this.

But definitely as of late, I would say there's a lot of people who are getting in who do not understand at all how the technology works. They're buying simply because the price has gone up and they just know their neighbor or their friend or their third uncle once removed or whatever it is. that those people have made money on it and they're like, Oh, I have to get in like, you know, I got it by before, before, you know, I want to get rich. What like, and it's just, it's, it's first of all, it's if you if any of you have done that, I would say, learn what it is that you've bought, you know, you really should only understand what it is that you're buying. and fully understand the risks. As we've outlined in this

episode, there are a number of risks. I didn't even actually, when we talked about security, I didn't even talk about the hack set exchanges, which have been huge, like Mt. Gox lost, oh gosh, I think it was like half billion Bitcoins or something like half a billion Bitcoins, which is, that's insane. It's worth a lot of money now. Yes. like I said, the security of these things hasn't been figured out. If you don't understand what you're buying, then you could very easily also lose your coins if you don't know how to secure them, if you don't understand how it works. And the other thing about buying something that you don't understand how it works is like, why buy it then? like if you if you don't really understand what could make the value of it go up like what makes it a

good investment then there's just i really don't understand why you would have bought it because maybe you've just bought into a massive ponzi scheme and you didn't know it like you really you know you should understand the technology and so what i feel like i've seen or what i'm seeing right now is that obviously there are people who are participating in this new financial ecosystem that do understand it and Many of those are kind of like the libertarians from the early days or the Silicon Valley technologists who learned about it and really thought it represented something new and a new breakthrough and wanted to participate in it and have also helped grow this ecosystem. And so there's some measure of demand in the space that comes from knowledge

of what it represents, but then there is this other demand that comes from people just seeing oh my God, the price has gone up and I can make money. And that is a terrible reason to do anything in life. And like I said before, if that is how you are operating, then you should be totally prepared to lose your shirts. And for people who do understand what it is that they've bought, they have gone in knowing just how much they could lose or how they could lose it. And so therefore they are putting in probably what is an appropriate amount of money. And then the other thing that I would say is that in terms of whether or not this is a bubble, there is obviously a certain amount of technology that's being developed or software that's being developed or projects being developed that do

represent new advances and will probably bring about lasting change and be widely used at some point. But there's definitely also a certain portion of entrepreneurs and developers in this space who are just trying to get in now while every every average Joe and average Jane are just throwing their money at anything that has the word blockchain in it. So for that reason, you should also be careful if you wanna put money in this space because there are a lot of unscrupulous actors right now who are trying to just capitalize on the frenzy and really don't care about building anything that will last and really don't care about being fiduciaries with the money that you've given them or maybe fiduciaries in the word, but just they don't care about

actually taking your investment and trying to provide you a nice return. They just care about taking the money that you've given them and buying a Lambo. So. Well, and there's also different classifications between all of these investments. There is tokenized securities, there's utility tokens, there's altcoins. Can you explain the difference between these classifications? Yeah. So a tokenized security is not that different from what we would consider like a stock or some other form of equity that we're familiar with from the traditional financial system. But what makes it different is that it comes in token form. And so it can be more easily traded. And particularly if it's, you know, maybe if it represents like equity from like a private investment, then that is something that in the

traditional financial system would probably come with some sort of lockup period, such as, you know, an investment in a venture fund. But here you can have a tokenized share of a venture fund that you can easily trade and probably without the lockup period. And there is a token that we have seen like that. In fact, there's actually more than one, but the first one was called the BCAP token for blockchain capital. And it was a portion of their third fund that was tokenized. I think they raised 50 million and did 10 million in these security tokens, basically. And because they were security tokens, they did register those with the SEC and only sold them to accredited investors, which are wealthy investors. And so the benefit though,

to those investors is that then they could sell them on the secondary markets and didn't have to hold onto them for the lockup period. So utility tokens different and it's something I think that is more kind of interesting, frankly, and takes advantage more of the unique capabilities offered with blockchain technology. And typically, they offer a particular function within the little mini economy that has been built around the token. So for instance, with if the Ethereum platform, Ether, which is the token, is used to power the smart contracts on the Ethereum platform. Another example would be Filecoin, which is a peer-to-peer network for file storage. And you can use Filecoin to, for instance, pay

for storage from somebody else on the network, or there's another network, Gollum, where you use the GNT token to pay for or sell computing cycles. If you're, let's say, you know, at night when you go to sleep, you can offer up your computer on the network and then other people can use the computing power on your network for work that they're doing. The last kind of like, I guess you would say category here, or well, there's really two more. So another one is what they call an app coin. And those tend to be a little bit more consumer facing. Some of the utility tokens are more what's called like protocol tokens where those happen more at the infrastructure layer. Whereas app coins are

things that maybe down the future as infrastructure gets built out, you or average consumers will be using just to interact with businesses directly or to interact with each other. And those are ones that will be more consumer facing. And then the last category that I would mention is just altcoins, which are typically coins that are just tweaked slightly from an earlier coin, which is usually Bitcoin. And the most successful altcoin is Litecoin, which, as I mentioned before, is it has faster block times, it's less energy intensive, and it is is often called the silver to Bitcoin's gold. So altcoins usually aren't that

different from Bitcoin in the sense that they typically act like currencies and just there are certain parameters around the way they work that have been tweaked. So I know we're running out of time today, but I want to end on kind of a fun note. So one last question for you. Why do people keep talking about huddling? So this is a fun kind of like inside joke in the Bitcoin world or the crypto world. And it comes from a drunken Bitcoin talk forum post a few years ago. And the reason for this expression, hodl or a hodl is that often people in the crypto space talk about holding your coins.

And the reason for that is that Bitcoin, which was the original cryptocurrency, was made, was structured to be deflationary, meaning there will only ever be 21 million Bitcoins. And so as time goes on and more people and demand for these goes up, presumably the value of each individual one will go up, which is in contrast to most fiat money issued by central banks which tend to be inflationary so the expression is to just hold and the value of your holding will go up but this person was extremely drunk when they when they typed their post about holding i think they were super upset that they had not kept held onto their coins and they had sold and then because the price had gone up they you

know missed out on a bunch of gains and so um now everybody just loved that post so much now they all talked about huddling that's a great story now we all feel like insiders well laura this has been such a great episode thank you so much for giving such a comprehensive overview of all the crypto 101 concepts great well thank you for asking the questions Thanks everyone for joining today's special bonus crypto one-on-one episode.
