I've had two banks warn me over using my accounts for crypto. They have their reasons - mostly citing anti-terrorism / money laundering laws. They might have alterior motives too - threats to their ability to tax the economic activity of citizens. The more people that get economically unpersoned by the banking system, the more call for citizens rights for access to money. Also, I rebel a bit by using cash frequently. It's a bit of a quiet war for sure.
