Before posting any question please try to search it on the search bar of this forum, as a month or two ago I have saw a thread the same as it, there a lot of people/members have shared their opinions/replies, there you can find the solution/answer to your question.
Forum search bar is pretty useless, you'd be better off using google instead.
That's true. I have tried using it a couple of times and google search is the better option.
But back to the topic. There are no Bitcoin banks. If you are trying to earn some interest on your Bitcoins, then you could try investing in a stable altcoin or something.
