Hey guys, I am new so be nice

So yesterday, the co-founder of Bitcoin said that he is selling his BTCs and then maybe moving to bitcoin cash! In less than 24 hours, coinbase add this to its wallet and then price were pumped up by a few small transactions to 8500$!
In a trade world, this is illegal, isn't it?
Shouldn't Bitcoin have some sort of self regulation to prevent people from doing this kinda stuff?
First you need to realize he is not the co-founder of Bitcoin, Emil Oldenburg is the co-founder of Bitcoin.com. That's a big difference.
We really do not know if Oldenburg sold all his Bitcoin he did not show any evidence that he did that. Well if he did that is his opinion and trading strategy I do not see any illegal activity there. He is famous in the crypto market so some traders will follow him and some will also take advantage of it.
I agree that there should be some regulation in trading crypto.
