BTC replaces big brother in transactions. But you need to have some sort of trust system in place for any transaction. You pay fees to big brother in order to be able to recoup your money. In theory. People still manage to get ripped off pretty easily using paypal and so forth. Accounts get hacked, etc. Obviously BTC has flaws. First they were worthless, but when they developed value the criminals started focusing some attention to them. Nothing easier to do than look for wallet files or break into servers doing transactions. I expect what has happened is only the start. It is probably going to be a few code forks down the road before some type of reasonable security is found.
