If you use a bad password, your Bitcoin will get stolen.

I think long-term, Bitcoin is a currency of the Internet. So, even if humans don't use it, routers will use it. Web browsers will use it. Web servers will use it.

It's probably easier and cheaper to counterfeit hundred-dollar bills than it is to counterfeit Bitcoin.

Within my social circle, there is a large group of people who will take bitcoin as legal tender; like, you can go to them and settle debts in Bitcoin, and they will happily take it.

China may censor YouTube. China may censor Twitter. They won't be able to censor Bitcoin. There's no central authority. There's no one you can go to and say, 'We're going to turn Bitcoin off.'

It's important not to think about Bitcoin as a replacement for cash or gold or something that works alongside that; it's to think of it as programmable money. And we just cannot even imagine what that will be used for.
