I still dont see the crime in it. Satoshi21 created in his basement with a simpel smart contract 21million tokens. He gave them away for free, with just a philospohy. After that the market went crazy, but it is not Satoshi his fault it hyped. The hype, what this coins stands for etc was all in the minds off those who bought it. There was nothing else.
That he was trying to cash out was no crime either, there is no law he could not cash out, and or unplug his site and delete his accounts.
I agree, some people even made few grands from it. If some people invested in this coin it was their choice and they are only to blame.
Sometimes I think, human nature being what it is, the only way to stop a dev from dumping when the market is high, is if they create a coin or token where they hold less than 10% from the start. A smart dev if they hold alot will sell piecemeal to the market giving it time to recover from the trades.
