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 ?
Why build a bank again when every Bitcoin holder is a bank manager of his/her own crypto bank?. You talking about security, when Bitcoin wallets like blockchain and Coinbase are already giving us that. Building a strucutre for a crypto bank is as irrelevant as developing a control social media for Facebook users. It is of no use really.
