  • Bitcoin is a new digital currency that is perhaps the best form of money that we have

  • ever seen. It’s important because most of us don’t understand money very well and

  • perhaps the concept that is hardest for us to understand about money is that money is

  • and has always been a ledger. And people often ask: "What is money backed with?" And the

  • truth is money’s not backed with anything. It has never been backed with anything. The

  • euro is not backed with anything in particular and neither is any other currency in the world.

  • And gold, for example for that matter is not backed with anything either.

  • Some people think that gold has value because we use it for jewelry but it’s actually

  • the other way around. Gold is valuable because it’s very scarce and because it’s very

  • scarce it has been the best ledger weve found in 5,000 years. In bitcoin we have something

  • that is as good a ledger as gold, meaning it’s incredibly scarce. There will never

  • be more than 21 million bitcoin. It’s even more scarce than gold.But in history we have

  • had this tradeoff between things that have been very, very good store of value like gold

  • for example and things that have been good for payment like the Portuguese escudo, the

  • U.S. dollar, American Airline miles, or Facebook credits. Those things are better for payment

  • but theyre not so good as a store of value historically. And the things that are good

  • for a store of value like gold are not good for payments.

  • In bitcoin we have something for the first time that is incredibly superior than anything

  • we have seen before as a store value and also as a form of payment.It’s hard to have a

  • rigorous discussion about bitcoin without understanding money. And the best way to understand

  • money is to understand the history of money. Anthropologists agree that there’s no tribe,

  • much less a civilization, that ever based its commerce on barter. There’s no evidence.

  • Barter never happened. And that’s counterintuitive to most of us because we are taught in school

  • that we first barter and then we made money because barter was too complicated.

  • Well, barter never happened and that’s one of the key myths about money. So then you

  • would ask the anthropologists, "So how did we do commerce before money if there was no

  • barter? There was no commerce." No, there was plenty of commerce and the way that commerce

  • would happen is that let’s say that someone in our tribe killed a big buffalo and I would

  • go up to a person and say hey, "Can I have a little bit of meat?" And that person would

  • say "No" or "Yes, Wences, here’s your meat." And then you would go up to a person and say

  • "Hey, can I have a little bit of meat?" and that person said "Yes, here’s your meat."And

  • basically we all have to keep track in our heads of what we owed other people or what

  • our people owed us. And then someone would come to me and say "Hey Wences, can I have

  • a little bit of firewood?" and I would say "Sure, here’s your firewood." And I have

  • to remember that I owe that person a little bit, that this person owes me a little.

  • And we all went about our business with these ledgers in our minds of who owes us what and

  • what do we owe to whom. Very subjective system often these debts didn’t clear or clear

  • in ways that were not satisfactory to both parties. Until about 25,000 years ago someone

  • very, very intelligent came up with a new technology that really took off. So a person

  • came to me and said "Hey, can I have a little bit of firewood?" and I said "Sure, here’s

  • your firewood." And this person said "This time were going to try something different.

  • Here are some beads for you." And I said "I don’t want beads. I don’t care for beads.

  • I don’t need beads." He said "It’s not about that. We are going to use beads as the

  • objective ledger of our tribe. Instead of each of us having to remember what we are

  • owed the beads are going to keep track for us. An objective ledger to keep track of debt."

  • It was such a successful technology that it took off and in a couple thousand years it

  • became impossible to find a tribe or a civilization that didn’t have some form of objective

  • ledger. In some cases it was wampum shells. In other places it was salt, in other places

  • rocks or beads. But this form of keeping track of debts with an objective ledger took off.

  • And anthropologists go as far as saying that if you describe a tribe’s environment in

  • detail they can predict what’s going to emerge as an objective ledger as money because

  • it’s always something that has six qualities.The most important of which is that it be scarce,

  • and it makes sense because if it’s not scarce we can create, you know, if we were to use

  • tree leaves for example, we could create debts owed to us out of thin air and that wouldn’t

  • be good. That wouldn’t be a good ledger. But it also has to be durable. If it’s something

  • that decays or corrodes it doesn’t store the information well. It has to be divisible.

  • It has to be transportable, recognizable and fungible.

  • This system really worked until about 5,000 years ago when trade began to extend a lot

  • geographically and we began to trade with other tribes. And different tribes were using

  • different ledgers so they couldn’t trade with each other. And what happened then, about

  • 5,000 years ago, is that gold emerged as the first universal ledger to keep track of debts.And

  • it was gold because it was universally scarce. That was the most important consideration.

  • But also it was very, very durable, fairly divisible, transportable, recognizable and

  • fungible. And that’s why for 5,000 years gold has been the best store of value we have

  • ever seen.

  • It’s incredible that today if you need to leave $5,000 for someone for your daughter

  • not your daughter or your granddaughter but some great, great, great, great, great,

  • great, great granddaughter of yours 40 generations from now – 900 years from now, we don’t

  • know how to do that. If you leave it in just dollars it’s not going to be worth very

  • much. We know of no security that will last that long. The only thing that we know can

  • carry value for that long is you need to buy $5,000 worth of gold, lock it in a vault and

  • give the key to that person 900 years from now. It’s incredible that in the twenty-first

  • century this is the best answer we have.

  • This is why bitcoin is so relevant because it’s the first time in 5,000 years that

  • we have something that is incredibly superior to gold in each one of the six characteristics.

  • It’s much more scarce than gold. There will never be more than 21 million bitcoins. It’s

  • more divisible than gold. Each bitcoin is composed of a million pieces called Satoshis.

  • It’s much more durable, divisible, transportable. You know I can have a Skype call from here

  • in New York to someone in Jakarta and I can see them in real time and I can hear them

  • and they can see me and they can hear me. It’s incredible the technological accomplishment

  • of that. But if after hanging up I want to send them one cent to Jakarta even though

  • I have the cent in my pocket and it will be trivial if they were here, we don’t know

  • how to do that. It’s not possible in the twenty-first century to send a cent to Jakarta.

  • One, because it will cost more than 50 cents to send it. Two because it will take a week

  • to get there. And three because just there are no systems to do that. Well bitcoin fixes

  • that and makes it real easy to send that cent to Jakarta or a million dollars to Jakarta.You

  • can attach a bitcoin to an SMS message or an email and send it for free and in real

  • time across the world. And it’s incredibly easy to verify the second you get a bitcoin

  • you know that it’s a good bitcoin. So it has all of the qualities of a great ledger

  • made in digital. And because of that it’s probably the best form of money weve ever

  • seen.

Bitcoin is a new digital currency that is perhaps the best form of money that we have
