It could be a scam if he can get people to send bitcoin thinking he will trade it for them. I would avoid putting money on his trades because there are very few people that can make money like that in the long term, particularly when using margin on short term trades. Having watched a few of his videos, I don't think he is one of the few that can make money doing that. I've seen a few trades that would of been big losers. I'm not sure if he removes videos or blocks comments when they go wrong? Is he trading a real money account in real time? I doubt anyone that can make money margin trading would waste time making YouTube videos. The fact that he has made videos about so many different services also raises alarm bells. Most people specialise in one field and don't go from one career to another in a short space of time. Has he answered the accusations from that ripoffreport site?
