We have to understand that there is really no regulation in place that actually get to see things go differently compared to what has been happening with the stock markets in which you can easily get jailed or get into trouble for manipulating the market as we have seen cases like that before.
Manipulation evolves just as much as regulations concerning the crypto market does. The manipulation happening in the stock market is less obvious, but less obvious doesn't mean it isn't there. Institutions know exactly how far they can go, and they also know how to make their trading patterns look as organic as possible, which can't be said about those who drive the crypto market.
Everything happening in the crypto world is so obvious and it almost looks like market makers aren't even bothered by anything, and why should they? Exchanges are closing an eye when it comes to their market makers, because they know they are gone when you limit their functionality as exchange.
In the end, people love pumps and dumps, which means that if they want to get rid of manipulation, pumps and dumps will be gone as well. In other words, be careful what you wish for.
