Dubai may be a fairly relaxed place and the Free Zones offer flexibility, but I'm confident that even the authorities there will not take kindly to a shady "crypto" business operating on their shores.
What makes you think he'd be looking to set up in business there? He's potentially got millions of dollars worth of bitcoin to live off and a name in this industry that nobody will ever trust or want to be associated with.
He makes me think it. He can't resist it, he's a narcissist remember
He thinks he is a big shot businessman and the failures so far and to date are not his or, if they are, it because he didn't get the right people and not at any point that it was his own flawed thinking and behaviour that was the issue.
So another business will pop up. Now, whether he chooses to attach his name to it so boldly at launch? Maybe, maybe not....
