If bitcoin bank will issue loans in bitcoins at a favorable interest, then I do not mind using such service.
Just need to very accurately choose the time when to take a loan, and when to give
If they do like this then it is a good move, and people like to take bitcoin loan in the bank. But how they collect interest is matter, because the BTC price will increase and decrease so how they calculate the loan interest. And this business will work out in a real world? I think it is profitable for users and loss for Bank.
