Any idea? Is there a new coin he is going to announce based on his own blockchain?
If he is hinting at that, then it's just going to be another scam shitcoin version of BCH and BSV. The thing is Roger, Craig and even Yang know they are just spreading lies and FUD, both when they claim they are 'unmasking Satoshi' and that BCH is the real bitcoin, they know it's all lies, it's their supporters and fans who have strongly bought into their ideas, they are the people being deceived by all this FUD.
But how can he succeed in this endeavor of ending btc dominance with his exchange?
Yang can't do that, bitcoin is not dominant because it is traded on an exchange, I think Yang, Roger, Craig and all their supporters should read the bitcoin whitepaper, Bitcoin is dominant because of its use case which neither of them can take away.
