The bank should offer bitcoin debit and credit cards and of course will operate bitcoin ATM machines. In the bank you can file a loan with your bitcoin or crypto as the collateral. Maybe even have the facility where you can deposit your bitcoin under the bank's safety platform.
Is this just a dream or is there a possibility that this can happen eventually maybe 10 or 20 years from now? Or maybe in the first place there is no need nor demand for this?
My answer is no, despite the overwhelming amount of "yeses" within this thread.
However, the reason is not that there is a lack of demand for such a facility, or even that it's not technically feasible - these prerequisites can both be fulfilled. The problems arise from the regulator's side, where with the tightening regulations, being completely legally compliant comes at an extremely large cost, especially when you compound that with the already high establishment costs of a physical storefront.
Maybe if you shifted the criteria to "virtual & physical" instead of physical only, there would be a higher possibility. But for a physically operational bank to completely shift their loan and savings denominations to bitcoin, all the while complying with every clause of every regulation, is next to impossible at this stage.
