I admire your friend's courage and self-confidence, the interesting thing is that when we put that courage into play, it seems like our luck changes, isn’t it? That's why I avoid bets like that based on word of mouth.
Well, for starters, he wasn't a friend, he was someone I knew on the forum as well as I know you now, which is almost nothing. But no, I don't think luck changes. He proved to be good at trades but making too many usually ends in screw ups like that one, that's why I was warning you about your trades on Betfury. Normally when you win it's best to take a break, we see too many stories on the forum where someone was winning, either in bets or trades, couldn't stop betting/trading and ended up losing everything. Enjoy the profits, you'll have plenty of time in the future to lose.
