If you feel like Bitcoin's too volatile, just just change the size in your portfolio to a point where you're comfortable with it. I would say, the only mistake is to have zero. You shouldn't have 0% of Bitcoin in your portfolio because it's really great as a non-correlated asset, and the only free lunch that we ever get as investors is having assets that are not correlated.

I think Bitcoin is the best form of money that's ever been invented. And I think the breakthrough in computer science that Satoshi Nakamoto came up with is a once-in-a-thousand-year breakthrough ... The ability to send money without a trusted intermediary to anyone on Earth almost instantly has never been possible. So, this is historically unprecedented.

Bitcoin has this one extra magical property that gold doesn't: It's like gold that can be teleported across the world. That's a very powerful thing—to be able to send value to someone across the world as easily as sending an email. And, in fact, this has never been possible before in the history of the world—to be able to send value to a distant person without anyone in between, without any intermediary, such as a bank or a nation state or government, helping you out to facilitate that transaction.

I think Bitcoin is the best money that's ever been invented, and I think it's going to become the global reserve currency ... I think it's going to overtake the US dollar in the next 20 to 50 years.

It doesn't matter how volatile an asset is to whether or not you should have it in your portfolio. If something is really volatile and that scares you, you can calibrate that with position sizing.

When a product has a network effect, it's the most important attribute of that product that gives it value.

You can store $100 million worth of Bitcoin in your head, and you can cross a border, and no one will ever know.
