There are already exchanges and wallets doing exactly that
The advantage of the banks, though, is that you could open two accounts, one for fiat and another for bitcoins, and then you wouldn't need to send fiat to an exchange to buy a few coins paying hefty commissions. In this way, the usefulness of banks consists in closing, or at least minimizing the gap between fiat and Bitcoin. It is almost a given that a lot of people would turn away from exchanges and web wallets to banks, especially long-term investors that don't need to buy and sell bitcoins daily
Bitcoin banks already exist in some countries. But they are in themselves the same freedom that was dignity bitcoin. I'm afraid that was not worse.
Could you name these countries?
There are already quite a few places you can get a Debit card that yo pay in BTC but can use as USD EUR etc. It would be nice if someone offered a credit card with a X BTC limit
I guess it doesn't make any sense
Since you would be still paying with fiat, and you would never know exactly what your current limit is, due to constantly changing exchange rates. Besides, you would most certainly have to pay hefty interest just because of that. I mean Bitcoin volatility which the card providers would consider as additional risk when loaning bitcoins to you. Maybe, I'm missing something, but overall it would be a bad idea
