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. If you want to earn then just hold your bitcoins in your wallet and wait for an inflation. That way you will get more profit out of your investment. The only way to save in banks is to convert your bitcoin into fiat currency and then deposit it on banks. But holding bitcoin is much profitable than savings on bank.
Exactly, to save your bitcoin the only way is to hold in your wallet whatever wallet it is. Because there are no banks that accept bitcoin right now. In holding it in your wallet you can get some profit whenever it pump. I also saved money in my wallet and I can say that this is very helpful because wallet serves as my bank.
