I dont trust to Mcafee at all. He is all the time manipulating some coins. Probably he is collecting and then manipulating the price using social media. He did it many times in the past.
Well that is what he doing with DOGE now. So I guess the best option is to counter his move on DOGE as he is pumping it, it is best to do a SHORT on DOGE so that when he cashes out, you will profit from the sudden drop in price.
