Market manipulation in memes

How „bad" is market manipulation in terms of legal consequences? I've made quite a chunk of SOL with not quite usual methods (no rugpulls or scams of course!)

But wondered how regulated memecoins are in comparison to stocks for example if even Trump himself can make and promote a coin with only 20% of the supply in circulation.

And also back to me if you can cash out or is binance making some back end checks?
