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?
I'm being nice. It's the co-founder of
Bitcoin.com. It's a very, very, very, very different thing. And this guy, Roger Ver, has been a huge supporter of Bitcoin Cash from before its hardfork was launched. There's nothing nefarious about Roger's interest in Bitcoin Cash. And there's nothing nefarious about him putting his money where his mouth is - selling his BTC to by BCH. That's fine! That's good! And it's also likely a move to build hype to get others invested. There's nothing wrong with that.
At worst, it makes this world of ours more interesting.
At best, it brings fair attention to a Bitcoin alternative that can directly improve upon some of Bitcoin's shortcomings.
