It seems that he is very active and kind of giving frequent signals, but apart from the effective antivirus, is there any particular reason to believe that his views are any better than others? I am just asking, as I have not bothered to research much 
I don't think so, sometimes he make a good reason for choosing coin in crypto but because he's a famous person there's a lot of people who follow his word blindly and make a pump and dump scenario. I don't follow his advice as I prefer to do research on my own, but I do thank him because out of the coin that he tweet, I owned three of them and make a lot of profit from that.
