When I was in Costa Rica a person asked me if I know a bank that doesn't take his money away, because sometimes money just disappears from the bank accounts.
With Bitcoin you can get hacked, you can lose your password, but at least you can really own it, and no bank can just randomly take away your money.
Just a few weeks ago Russia did the same thing for international accounts of people there, which is in the news, but it's happening in lots of 3rd world countries every day.
