your bank can close your credit card and freeze your account and there's nothing you can do about that.
bitcoin allows you to become your own bank, you can even loan funds to other people without anyone being able to stop you, no credit card can do that.
There are very few bank users who worry about having their account frozen or their credit card's line of credit frozen, because most people aren't terrorists or drug dealers. So tell me again why exactly everyone is going to start using bitcoin? Why would I want to loan money to a friend? That sounds like a bad idea to begin with, but I suppose if I really wanted to, I'd just write him a check?
the IMF tells you black on white that it considers confiscating people's money and you still don't care.
what else needs to happen for you to understand that sooner or later they are going to rob you.
there won't be any more obvious signals than this, the next step is you wake up one day and your bank account is frozen.
just like this guy did:
