Hi, guys! I'm not sure such banks are exist but maybe you know one.
None for now mate, but maybe in future you will get some, the only agencies that are operating like banks for us are the third party agencies like local bitcoin and other ones where you can change your cryptocurrency to fiat, and maybe you can then take the cash to your bank, and even if you receive large amount of fiat from these local exchanges, the banks will still put and eye on it and could block your funds so you can explain how you got such money, but I believe that very soon, we will have some banks that will have no choice than to accept cryptocurrency transaction even if it is against their will, that will be when the crypto industry has been regulated and government is use they will be getting their complete tax money from traders.
