I watched some of Suppoman's videos over the last month. They are mostly fluff and hype, but I did learn some things from them.
I don't think he is a total fraud, but I saw a few red flags. He was all over the place, promoting one coin one day saying it was a long-term hold and saying he was going "all-in" on something else the next day. I also noticed he has not posted a video in 6 days after shilling Bitquence and seeing it go far below ICO levels. Previously he was posting every day.
He really is quite bad at picking ICOs, but I still think he had some good insight on long-term value of coins he had researched. Its just impossible to know if he got paid from certain ICOs to shill or if he is just bad at picking.
RE: Suppoman EXPOSED as a scammer. Why you should NEVER listen to any youtuber and always do your own research.
