If I decided to save bitcoins in bank, how will deposit rate be changed compared to dollar or other currencies? Will it have much lower percent?
Its sad to say but there are no bitcoin banks existing online.
Wow this isn't true! There are several bitcoin banks online - Coinbase, Circle, Xapo!
OP is talking about a bank that is giving him profit and none of these have that. and besides Circle was mostly about buying bitcoin and it has stopped that too!
the best term to describe these services is "an account to hold bitcoin" and nothing more.
Yeah, and besides these are just wallets. They are only used to store Bitcoins. They cannot be classified as banks because they do not offer loans or interest on the coins you are storing. They are just making profit from fees and the fluctuations of bitcoins.
Now if you want to store in the bank. You should convert first bitcoin into fiat then put it in the bank.
