After this post, I will not comment more on this Kevin Davey guy, because everything I say in this regard is just speculation.
Everything is possible, and maybe he is really a fantastic trader. But to me, he does not seem like a successful man, at least not in trading.
I have no clue about this trading worldchampionship, but this sounds just superstupid to me. If you are a "champion trader", why you dont just make your millions quiet and in disguise, and then enjoy spending it and just having a fantastic life ? And even if this championship is real... even a broken clock is right twice per day. Having a good performance over such a short period of time does not make a successful trader in my opinion. Everyone can load up on risk and then either be a star or a big loser in such a competition. You have countless trading competitions each day on the internet, and all the time you have some noobs winning with performances like 300% in 2 weeks. There are all their yachts and Ferraris ?
Everything is possible, and maybe he is a fantastic trader. But to me, he seems more like a vendor, trying to get people into his stuff and make money from them. He sells books, he sells his trading systems... if one is such a super trader, can he not make enough money from his own trading ?
I do not call myself a champion trader, I never participated in such "trading championchips". But I am still happy with my performance and can live the life I always wanted, as a result from my trading. I would never want to sell books, courses, my "strategies" or something like that to anybody. So much extra hustle and work for a few extra dollars ? If my trading would not be profitable, then maybe I would consider other ways of making money. But even then I would probably not want to sell saltwater to the thirsty ones.
