I wouldn't call what Tom Lee  does, speculation. he is mostly full of hot air and is hyping up bitcoin with his perma bull price guesses that he keeps throwing at people on the internet. and I have always said he is just advertising his business wanting to get more money flowing in.
because he is perma bull and has always been predicting rise, he is now at least predicting things in the same direction that the market goes which may create the illusion of him being good at what he does
