Just as the Internet brought the cost of disseminating information down by an order of magnitude, bitcoin brings the cost of transferring ownership down by an order of magnitude.

Bitcoin is two things which share a name. One, it's a payment system, and two, it's a currency. You use the Bitcoin payment system to send bitcoins as currency from one account holder to another. The transfer is instantaneous, carries no fee, works anywhere in the world, and is private.

My salary is converted to bitcoin, and taxes are taken out. You have to do all the tax computations in dollars because the IRS does not deal in bitcoins.

That's a term that I really like - 'permissionless innovation' - because anybody who has an idea and has a solution can tap into or can leverage the Bitcoin blockchain.

That was the moment I wanted to use bitcoin: when I saw Harriet Tubman on a $20 bill. It's like, when you see all the slave movies, it's like, why you gotta keep reminding us about slavery? Why don't you put Michael Jordan on a $20 bill?

I don't think Bitcoin cares what the Chinese or American politicians do.

The rudest possible gift is a gift card. It means you think the person is stupid and has no interests. The only good gift card is Bitcoin. You practically have to be a hacker to know about it.

Bitcoin is complex: the entire private and public key issue, the transfers, the mining of bitcoins... but if you tell it as fiction, people would understand and remember.

Bitcoin and digital currency is just this thing that was always going to happen.

Bitcoin never sleeps. We need to move quickly and grow quickly and do everything sooner rather than later.

I trust bitcoin more than I trust my bank.

There is nothing that Bitcoin can do which Ethereum can't. While Ethereum is less battle-tested, it is moving faster, has better leadership, and has more developer mindshare.

We really think of Bitcoin as a global, interoperable payment network instead of a store of value.

What bitcoin does better than the current financial system is it's a better stored value globally. There are a lot of countries that really don't trust their banks or their currency, and bitcoin is an alternative.

Well, bitcoin is a currency. Bitcoin has no underlying rate of return. You know, bonds have an interest coupon. Stocks have earnings and dividends. Gold has nothing, and bitcoin has nothing. There is nothing to support the bitcoin except the hope that you will sell it to somebody for more than you paid for it.

In 2017, people have realized there isn't going to be one crypto to rule them all. You're seeing vertical solutions where XRP is focused on payment problems, Ethereum is focused on smart contracts, and increasingly, bitcoin is a store of value. Those aren't competitive. In fact, I want bitcoin and Ethereum to be successful.

If the U.S. government tries to restrict or clamp down, that just means there will be many more bitcoin businesses in Hong Kong and Singapore, and all those Americans will miss out on all the opportunities.

Like the Internet, Bitcoin will change the way people interact and do business around the world.

I believe that Bitcoin holds value as a form of 'good money' that is superior to any previously discovered or developed form of money.

There is a lot of volatility in the digital asset market broadly, and certainly that is true in the bitcoin market. It's been true for XRP, and I think that's because these markets are very nascent.
