Wondering how he gets so many retweets/favs, first time i heard of him, not many of the big industry names follow him. Yet he knew about bitstamp ahead of time. Sticking with ETF positive news prediction, seems like the kinda information someone like him might have gained access to.
Just speculation, but there are tweet follower services which you can pay and they will add thousands of random followers to your account for a small price. I mean 6k followers is decent, but its certainly nowhere near celebrity status. There are a ton of small 'btc pumps' twitter accounts that have more than 2k each, and from the way they tweet, are probably ran by 17 year olds.
