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
Maybe it possible, but what was the possible collateral you offer, if the Bitcoin bank give a high amount of loans with fair interest how they can assure that you paid it in time? I don't think so if it is possible for now but we still hoping that it will be happen in the future.
