if i build a bank of bitcoin that operating like a traditional fiat money bank when people can save the money and get interest for their saving and also people can get a loan from my bank but the fiat money is change for bitcoin, the question is would you guys trust me to save your bitcoin on my bitcoin bank that i want to build ?
No, I do not trust any banks that use bitcoin as their primary currency. because bitcoin is volatile everyday and worse volatility is more than good. Besides, banks not only trade or lend capital to get profits, they also have to buy government bonds and safe bonds to have money and maintain the operation of the business. I think you need to have a better understanding of how the bank works to open it.
