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?

-------------------
EDIT-24/12/2017: Here are a few updates, to prevent people from making wrong assumptions from my original post:

1. I meant co-founder of bitcoin.com, and I made it clear a few post later!

2. bitcoin cash reach to 8500$ even 9000$ for 2 hours, in coinbase.com. The reason was inside trading (google it,plz)

3. The whole topics of this discussion was started about the banaza move that basecoin.com and co-founder of bitcoin.com pull off! This move not only made some people lose their money, but also it caused the price of BTC go down by 30 to 50% over a few days!

Did you guys teach your family members on how to access and use your Bitcoin in case you will die?
Do you want to take your Bitcoin with you when you're gone?

Let me hear it from your own opinions...

I couldn't wait any longer and jumping into cryptocurrency pretty late. I understand I have invested at the high end as of late, but with the rapid growth over the last several weeks I would be a fool not to jump in.

What are the predictions of the bubble before it bursts and drops back down?

Also, I imagine it should become my goal, as an investor, to actually use the bitcoin for what it was created to do. Peer to Peer purchasing in a free market, not relying on the banks or 3rd party taking their cut. Where can I begin actually using bitcoin to purchase normal household items?
