You mean the CEO of Bitcoin Cash -- Rick Falkvinge -- isn't allowed to trade bitcoin?
If he trades based on insider information, as you implied, and this can be proven in court, he will go to jail in most countries in the world.
Well, most likely not jail, but a hefty fine

Maybe start a twitter campaign to jail the CEO of Bitcoin Cash?
For the record, there is no Bitcoin Cash CEO. That doesn't even make sense. How can a blockchain have a CEO? That letter was satire. The people with "inside information" are the miners and the whales battling it out right now. I have no idea how this mess will play out, which is why I hold both BTC and BCH. I am leaning towards BCH though.I guess that you are conceding that some folks are fucking nutjobs, including that Rick whatever his name is who proclaimed to be the CEO of Bcash as a kind of pump "satire", as you call it.
Sure, it is understandable that cryptos are generally unregulated, and largely decentralized, but if the SEC considers some behaviors to be bordering on the promotion of securities, then some players could get themselves into trouble by pumping such, no? Even if they later proclaim, "satire?"
