People think about Bitcoin incorrectly. They think about it as currency or about gold or hoarding, speculation, about how much money do you make. When really, what it is is an API for programmable cash transactions.

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.

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.

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

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

Think of Bitcoin as a bank account in the cloud, and it's completely decentralized: not the Swiss government, not the American government. It's all the participants in the network enforcing.
