Everything HEX related is a scam, because obviously this is another classic Ponzi scheme. So I don't really understand why people still commit to this project or the people behind. There have been a lot of write-ups exposing the HEX project itself.
To the OP, thanks for your warning, and again, I do hope that people will not blindly trust on this kind of Ponzi scheme just because the people behind promise them good returns.
