Gambling is a separate business from altcoins or faits, while gambling is completely a lucky outcome, altcoins is based on knowledge and experience of the altcoins market, especially when to enter and exit a position. Bitcoin drives the entire crypto market, one of the reason for high dominance rate based on it's consistent demands overtimes. In my opinion certain altcoins out there has great future and without altcoins, Bitcoin may not strive alone, there should be a competitive environment or market for all traders/investors to to make their choices.
