You bring up a very valid point @hilarski.
Sadly, the cryptocurrency world does get egg on its face with stuff like this.
Charlie Lee tweeted that he unloaded all his LTC a couple days ago. He is one of the leading faces in the crypto world and unloads just before a crash. I am sure that it is purely coincidental since he doesnt have the ability to pull $200B out of the market. Yet it does give people fodder to chew on.
McAfee is a wild card anyway. If he is going to give his two cents, which does carry weight, it should be on larger coins since he does have the ability to move things. With smaller tokens, it doesnt take much to get them flying since they have little volume.
That is how people get hurt in the pump and dumps. I have no problem with his bitcoin calls (and bets with it) since he wont move the market simply on his word.
