I can imagine how much money he has been getting it by promoting the ico. Each ico must pay 100k - 500k dollars for each advertisement through his twitter. i'm not getting any surprise when see he was getting charged by IRS.
In 2018 I think he made a lot of money from promoting ICO on his twitter, maybe he even made about $ 20-50 million. And all the ICOs he promoted are scam and people still support him very much, unbelievable
