Banks will take up anything that they can charge commission on. It wouldn't come as a surprise if there are banks accepting crypto, but I would be cautious about fees. P2P networks tend to be much cheaper. You might even get a better price from your online exchange.

The problem is the countries where regulation prevents banks from using it, like what happened in India recently. Also China, Venezuela, Turkey... there are many countries where the government will step in and try to block the transactions if they somehow think they are losing out on tax
