There is Switchdex and I do think sincerely that is the decentralized exchange McAfee is trying very hard to copy. Nonetheless, I think people should very care patronizing his exchange. I find it difficult trusting a man who always has a smile plastered on his face. In the case with McAfee, a failed past is a cause to worry about.
Well it looks like McAfeeDex is just a clone exchange from Switchdex.
Even support button on McAfee is directing to Switchdex telegram

It is very laggy and very white
