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.
Yes it's up to you as you can save bitcoin into bitcoin wallets like blockchain or coinbase i would suggest coinbase which is much simple and easy to use then once you have enough bitcoin then exchange it for your local currency from a trader at localbitcoin.com.
