That is a major point of bitcoin. You are your own bank, you are the one controlling and safe-guarding the money.
I actually prefer bank to guard my money, at least I blame them for losing my money.
Well you are not alone then.
Some bitcoiners still now prefer to store their bitcoin on exchanges and let the site hold and protect the bitcoin, even after the hack and bankruptcy of mtgox.
That's hilarious actually. One of the most important advantages of cryptocurrencies is that you are your own bank.
