Okay, this idea makes me think in a different direction....................
Most of the modern players in the market are not modern at all. They have there for decades, if not centuries and they know how to survive. In the end they realize what needs to be done for their own survival.
I think for now, coexistence have to be the key, Even they feel the pressure that's been building up for last ten years. If they didn't feel it before, then they definitely felt it after 2017. Perhaps letting the banks know that customers are interested in crypto can be the impetus they need to move in the right direction.
I am no fan of banks or the banking system but that will not make them go away. Probably we should seize the initiative and start a dialogue by letting them know our interest in crypto.......
