It's been a 34-year old who worked (until recently) in marketing for Mass Mutual Life Co and has a 2-year old daughter who has been the leader of the GME trade. Keith Gill goes by "
DeepF____Value" on the forums. He started his trade with GME in the summer of 2019.

I think one major concern is people want to try to emulate this (and subsequently lose their life savings which happens all the time on r/wallstreetbets) but it was basically the equivalent of winning the lottery and was extremely lucky.
Although he is a CFA and has a youtube channel ("
Roaring Kitty") where he talks a lot about his pick in detail (doesn't have very many videos)...So, he certainly has SOME knowledge.
