Bitcoin is hardly to be saved in a bank accept it is exchanged in a local currency of the land. This means that you must exchange bitcoin to the value of the local currency before you can make a deposit in the bank. i think bitcoin is mainly installed in the bitcoin wallet.
if the point is about saving bitcoins in some safed place - why not to chose one of bitcoin wallets? There are different kinds today. And it's right that novadays to hold bitcoins in a bank you need to cash it out in fiat of your country first, becouse there are no banks that would work with bitcoin directly today.
