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.
Hey great, even I am using coinbase wallet. Its seems to be good and as a security reason its not accepting VPN. Even I just created a account in Localbitcoins.com and I noticed when we transferred to this trading site wallet then its get logging in when we save the user and passkey. Please check and use both according to your convenience.
