What you called more like standard gambling, but there are platforms where you can besides the classic games, such as staking platform tokens and earn more from it or participate in tournaments. At the last tournament I won 200$, it's not a lot of money, but it came to me very easily. So if you don't know what to do in the cryptocurrency market, try to participate in a Fairspin tournament, play their games or bet on TFS it's a great chance to win some extra money.
