so i wanna know from all the bitcoiners here is there a some kind of bank where i can deposit my bitcoins and get safe transactions and not worry about theft or lost of wallet ??
Bitcoin was invented that you do not need any kind of bank anymore and you're asking for such a service?
I will never understand guys like you sorry!
Make a few back ups of your wallet.dat and a loss will not happen!
Also theft won't happen when you store your coins wisely. Furthermore there are several good hardware wallets which are pretty simple to use.
