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?
Your question is pretty confusing since there are currently no bitcoin banks that are available to deposit money in, maybe you may be talking about online wallets?
There is really no interest you can get from banks, but if you hold bitcoin for a couple of years it will most likely rise in value since bitcoin usually rises in value over time.
It is very a confusing one, lol. @vaxo_nba, there is no bank that is accepting bitcoin because since bitcoin is decentralized and they can't even touch it, maybe that is why bank don't have an interest on bitcoin itself. But I know that in the near future there will be banks that will accepts bitcoin, even though, I will still use the hardware wallets to save my bitcoin and so that I know that my bitcoin is in the safe place.
