That's what we think right now. But SEC can come up with a reason if they want to. If his company is registered in US and he is openly manipulating the price of the tokens by tweets, then the SEC can easily come after him for market manipulation.
Are you talking to me? If so, not that much. Currently only up 300% (2000% during the bullrun 2021). You are absolutely right, crypto currently is the wild west. This is simply because 95% of coins have absolutely no value outside of speculation and are impossible to evaluate. Still, assuming a 3+ year old memecoin will go 200%+ because it is listed on binance is something different.
