Im sorry but trading an altcoin gambling ? No I dont think so. Altcoins have made people millions $$, coinmarketcap reports daily volume of trades to 20.000.000$.
Trading an altcoins is not gambling per se if comparing it with visiting gambling sites and betting on casinos and matches, but people use to say it is gambling to let other people know how fast they can lose money because most altcoins are highly volatile.
