Coinbase froze everyone's accounts (to prevent a selloff) while cashing in on insider knowledge that they were going to start supporting Bitcoin Cash. Then as soon as they sold off and the market dipped, they unfroze everyone's account. But instead of being in jail, they just keep getting away with it.

You (and everyone else ostensibly affected) have had like 7 years to sue over this if you could prove it.

This type of behavior is what the SEC was made to solve. But to be honest insider trading is behind MOST hedge funds and other firms with unusually gains. And politicians with big gains. It’s a huge problem that won’t get solved. Maybe taxing them is the only way.
