From my perspective, trading bitcoins or altcoins can be considered as gambling, with a much lower level of risk, of course. When i trade i'm researching coins same as some sports gambler research football teams. In both cases it's gamble if you don't have some reliable insider info..
if you compared trading with sports betting yeah it's makes sense both are requiered some research to maximize your chance to win and get profit but if you compare trading with a casino games like blackjack, roulette , lotterry , slots machine , dice etc could you still call it as same thing as trading ? no of course not.
