Against banks? I love the enthusiasm but this is not the way. Banks as a whole have many of the best lawyers in the game on retainer (possession is 9/10ths of the law, and this industry banks on that and make bank.) The best crowdfunding campaign in history* is 800 million. The banks would be willing to spend at least that in their own defence.

*not including investments (nor blockchain)

Plus, a progressive lawsuit in this environment? Might backfire spectacularly - right now banks are cautiously picking on ‘safe’ targets. But with a green light from the supreme court the banks could go full Nazi. Yeah - there’s nothing good I can reasonably expect here.
