very surprising the bank decided to accept Bitcoin, but what's in my mind
1 . how do they divide the interest system
2. whether the bank will provide a median value for the bitcoin price, if it is too low the bitcoin owners will lose for sure
success will be far from expectations, if in my opinion if it is too big a loss for bitcoin owners
1. Bitcoin is not a currency that is impacted by inflation. So I don't think that there is a need to compensate the users with interest payments, if they chose Bitcoin. Unlike fiat, whose purchasing power goes down every year due to inflation, Bitcoin is essentially a deflationary currency whose purchasing power either remains stable, or increases with time. So it doesn't make sense to allow interest payments.
2. This is problematic, since there is no centralized organization that can decide on the exchange rate. My solution is like this: If the bank opts for a particular exchange to trade its Bitcoin, then it can use the prevailing exchange rates from that platform (similar to fiat forex, the buying price and selling price may be different).
