Entrepreneurship is really hard and painful - I'm not sure I'd recommend it for anyone who can't handle the extreme stress.

We can code wills, escrows, trusts, notaries, revokable charge backs, proof of contracts, intellectual property enforcement. What Wall Street does can be done in code by Bitcoin.

The ledger, the distributed database - it's called a Blockchain - is held in the cloud by all the parties involved. It can't be broken by any of them. It's cryptographically too strong. You would have to compromise the entire network to take over Bitcoin.

Money is a bubble that never pops. It's a consensus hallucination.
