...I will say this... Satoshi put so much power in the hands of users that every time (so far) someone has tried to control Bitcoin they have been ruined in the end. We are watching this happen with the BCH drama as it unfolds.
I believe the banks will face this same fate when they try to take control. Does not mean they will not cause us problems in the meantime though.
When? they are doing it right now under our noses.
