But at the Quality Mart on the corner of Boston's Mass Ave and Beacon Street, even though Bitcoin has lost more than half its value since the start of the year, folks were still buying. And, in fact, there are plenty reasons to think today's price is still a hot air balloon, with nowhere to go but down. That, however, is a story for another Thursday. Support Provided By: Learn more.

Judy Woodruff: You have probably been hearing a lot about the digital currency Bitcoin, and the technology behind it called blockchain. You may have had the time, though, to ask, what is it and why would you want to use it? Our economics correspondent, Paul Solman, is here to help explain. It's part of his weekly series, Making Sense, which appears every Thursday. Paul Solman: Think of this story as news you can use — how to buy Bitcoin, and know what you're buying.

You give it cash, and it gives you Bitcoin. Paul Solman: True, I could have just gone to the online currency exchange Coinbase, which, in the midst of this cryptocurrency craze, now has more account holders than Charles Schwab. Chafik Hamadeh: I thought it was going to be a waste of space, but I was very wrong. Chafik Hamadeh: It brings in a lot of traffic, people that normally wouldn't be coming to this area.

Paul Solman: And how much money does a typical customer put in, as near as you can tell? Chafik Hamadeh: A lot. I have seen people put in a lot of money in that machine. Paul Solman: Really? Chafik Hamadeh: Yes. I have seen people put in thousands. Paul Solman: Are you amazed when you see it?

Chafik Hamadeh: I am. I'm kind of shocked. Paul Solman: And the higher Bitcoin's price, the nuttier things get, says Narula. Neha Narula: This technology is really exciting. Paul Solman: Hey, you can even see the mania at MIT, in its Media Lab's insanely popular cryptocurrency design class, standing room only. Man: Today, I'm going to talk about signatures. The backup phrase is literally your personal key, a dozen words in a particular order.

And so these are just 12 sort or random words, all simple words. Neha Narula: Yes, English words. Paul Solman: Yes. Neha Narula: … you can use those 12 words to get your money. Paul Solman: But if you lose the phrase, bye-bye, Bitcoin. Neha Narula: The company that made this app doesn't have access to your money at all. Paul Solman: Forever. So, now I'm writing these down.

Neha Narula: Yes. Paul Solman: I have to do this, so that the camera doesn't see. And, normally, I shouldn't see either. Paul Solman: You know what? Paul Solman: I'm now going to put it in my wallet. Paul Solman: But, of course, I almost left my wallet somewhere yesterday.

Neha Narula: Exactly. Paul Solman: That's my leather wallet. But I need to get my smidgen of cryptocurrency into the cyber-wallet. Neha Narula: You're going to scan it right there. Neha Narula: I think it worked. Paul Solman: And then you put some good old-fashioned paper money into the automated teller machine. And let's see. We put it in here. Neha Narula: You're going to get. Paul Solman: Sixteen-then-thousandths of a Bitcoin? Neha Narula: Man, this thing charges a lot of money.

Paul Solman: OK, without spooking you with the highfalutin math that goes into actually buying and spending what's in your wallet, hacker-free, the basic idea is simple. Neha Narula: Really, it's an entry in a ledger, except, instead of a financial institution holding this ledger for us, there's a whole bunch of nodes all around the world that are running this computer program that takes care of the ledger for us, makes sure all the transactions are correct and keeps track of who has what Bitcoin.

Paul Solman: And that is the Bitcoin blockchain, a chain of computers linked through the Internet, all using the same software, to record and verify every Bitcoin transaction. And, therefore, nobody can cheat because everybody is watching. And no one controls it. It's controlled by everybody altogether. Vikram Mansharamani: It's a distributed form of trust.

Paul Solman: A single individual can't corrupt the blockchain, says investment guru Vikram Mansharamani. But we don't know if somebody cannot figure out a way…. Vikram Mansharamani: That's true. Paul Solman: … to manipulate an entire network.

Vikram Mansharamani: Sure. Paul Solman: Indeed, there's speculation, and some evidence, that Russia is both mining Bitcoins and hoarding them. And with the invention of Bitcoin, I could transfer a token, a digital token, that had value to you and I could do that without a credit card company or a bank or PayPal or Venmo or any of those things in the middle. So just like I could give you a 20 dollar bill, I can give you some Bitcoin. There are at least hundreds if not thousands of cryptocurrencies right now.

We design a new one that works slightly differently than Bitcoin, and we see how that goes. One thing differently could mean is it processes more transactions per second, it makes different trade-offs in terms of security versus ease of use.

Some cryptocurrencies have fundamentally different designs, some of them are more programmable than others. I think that is probably the second biggest. Giant electronic billboards display advertisements for cryptocurrency investment companies as commuters arrive at Canary Wharf tube station in London, Britain on April 6, If somebody got 51 percent of the processing power in the network, they could theoretically rewrite history and change the state of transactions in the ledger.

But what they could do is they could change the transactions in the ledger so that maybe they paid you, they could make that go away and they could pay that money to somebody else. And it might be the case that right now someone does have that.

Everyone is really excited about the blockchain because they hope it can be used for more than just cryptocurrencies. You know, you could theoretically create your own blockchain which would have its own network. No one could cheat cause everyone is watching. Tuesday, Feb 9. The Latest. World Agents for Change.

Watch Now. But from the point of view of the Bitcoin users, they see these controls as sort of arbitrary and pointless. Marc Hochstein: Yes, they would definitely use that word, tyrannical. One of the most infamous uses of Bitcoin is the Silk Road. So can you make a purchase with bitcoins without actually owning any? And BitPay, a payment processing company for merchants handling transactions in bitcoins, is part of that configuration of pipes.

Here Pair explains more about the everyday transactions that give Bitcoin its value. Stephen Pair: BitPay does payment processing. So a merchant wishing to use Bitcoin as a form of payment, or provide that as a form of payment to their customers, would come to BitPay, create a merchant account and then they could be set up within a few minutes to start accepting Bitcoin as a form of payment on their e-commerce site or even at a point of sale.

Stephen Pair: A lot of various kinds of e-commerce companies, a lot of companies that are more internationally focused or they sell to international markets. About one in 50 credit card transactions that are conducted internationally are actually fraudulent, and so by using BitPay and Bitcoin as a form of payment, companies can eliminate that credit card fraud. Stephen Pair: Well, PayPal is an account-based system, so it suffers from a lot of the same kinds of frauds in areas that you see with credit cards.

A Bitcoin payment is a push transaction , where the sender is actually creating a transaction and digitally signing it, sending the exact amount of money to the recipient. Pull transactions are the source of most of the fraud that occurs with the credit card. How quickly does this transaction get made? Stephen Pair: It happens within milliseconds, so our merchants can set their prices in dollars and they get paid out in dollars. And Bitcoin just serves as the payment mechanism.

And by that I mean that when I receive a Bitcoin transaction, I can go verify in a few milliseconds if that transaction is valid. On either end of that, I can convert some other form of currency or anything of value into Bitcoin, then use that as a payment mechanism.

And then on the receiving end, I can turn that back into whatever I want to actually hold. Stephen Pair: No, we have local retailers. They surpassed 10, merchants in September. Follow paulsolman. Support Provided By: Learn more. Tuesday, Feb 9.

Tonight, he looks at whether the price of bitcoin is a bubble? This story is part of his weekly series, "Making Sense". Back when Mexicali Burrito's David Zimel first accepted bitcoin a few years ago, it was worth — well, about the price of a burrito. I think we ended up with about nine bitcoins. And we just kept on pushing.

We wanted to turn it into real cash, we wanted to turn it into real cash and we finally did. I wish we would've held on to it a little longer cause it would have been worth a few thousand dollars. No, we have no idea what to do with it. I wouldn't have any idea on how to exchange it or what it's worth. No wonder. When Zimel cashed in his bitcoins, they were worth just a few bucks.

So, how can it be a currency if you never know its current value? It is developing many of the qualities of currencies but it isn't yet filling the basic role of a currency which is to enable transactions. You do need some more stability in the value of it before it gets truly adopted as a currency, not as an instrument of speculation.

Today it's de facto an instrument of speculation or a means through which to fund illicit activities off the grid. Bitcoins and sort of other cryptocurrencies live outside of the traditional banking network. And in fact are intended to do so by design. But local restaurants like Veggie Galaxy in Cambridge that used to take bitcoin don't any more because the value fluctuates too much, plus it's too cumbersome for petty transactions.

Can I buy my lunch with bitcoin? I'm sorry, we used to, but not anymore. We actually had an ATM. But we don't have it anymore. I'm sorry. For cash, you can pick up designer bags by the dozen, a pair of Shaquille O'Neal's hard- to-fill shoes, even this Poppin' Fresh pendant whose provenance can be traced to Boston mobster Whitey Bulger. You sign up an account and then we can meet over there at starbucks and we can transfer money at that time.

Regulation at this point, we can only sell and charge a small fee. But buying? Not at this point. Yes, only 90 percent of market value, plus a small transaction fee. And yet, despite all the hurdles to using it, bitcoin, and its underlying Blockchain technology, are seen as fat city.

Consider the recent rash of conversion experiences. In January, a company with nine Hooters franchises put its loyalty program, the Hooters Hoot Club on a Blockchain, and its stock price jumped 50 percent. But it's very hard to know what its intrinsic value is and it's very hard to know what it's legitimate use is. It certainly looks like a bubble to me. It reminds me of the Internet phenomenon, the Internet bubble, where people would add the dotcom and their stock price would go flying up — exactly comparable in my eyes.

So, is bitcoin a bubble that's already bursting, plunging by two-thirds in just a few months? Or a great investment that's up more than fold in the last five years? The first lens is microeconomics. Normally, when you have higher prices for a good, you should see less demand. When higher prices generate more demand, we have a bubbly dynamic that results in higher prices generating more demand, generating higher prices, et cetera. In other words, instead of turning off buyers, the rising prices are attracting them, triggering another lens: buying an investment on credit.

Are people borrowing money to invest in something because they are so sure it's going to continue rising? And in fact, we've seen that recently. We saw this back in the s with radios and cars. You saw it during the Internet bubble where the Internet was going to change everything and in fact you can see it today in this crypto domain, where this is the new form of money. Digital gold.

Think of a speculative mania as a fever spreading through a population. How many people are left to infect? Well, if everyone is infected, the disease has run its course, we're done! No idea at all how much of the price is attributable to actual fundamental interest in a non-printable currency versus "this is a party, it's rockin', I want to join it. This is Paul Solman reporting.
