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?
What you mean about bank? Knowing that there are still no banks that do store bitcoins on which our own wallets serves already as bank on holding up our bitcoin. Its the best thing to store up our coins and be thankful on that rather than letting centralized banks do make handle of your coins. Better to keep it on your hardware wallet and just put up good security on it.
