Eh. I'd cut Mat some slack. He had the right intuition all throughout the bear market, when a lot of bulls were still (or: again, and again) in denial. And despite what some people like to say, intuition is a big part of trading profitably.
My advice: develop some basic trading system that works for you, filter out everything that is not part of that system, and see if he can make it work better than his previous trading attempts.
Yeah, that's great. But if what I'm reading lately is correct, that he has 13 coins and lost $5k trying to trade, that means that instead of having twice as many as me he instead has slightly more. How long until I'm ahead, being in denial all the way down and buying a bit every month?
