There is an old Japanese saying: "Every person wears 3 masks. One you show to the world, one you show to your closest friends and family and the third one you don't show to anyone but yourself."
Rest assured that most you think you know about people, is still based on the assumption they show you who they really are.
That said, I don't think it is wrong to make the assumption that someone did not beat the 60% CAGR of BTC, as even 99.9% of this board did not beat that.
