it really depends on the player himself, if he knows or very familiar with at least one sports, football or basketball, better explore his opportunities first in sportsbetting. because the more you know about the sports, the better chance of winning. but if you will play with casino games, which is mostly based on luck, be ready to lose your funds all the way.
i find sportsbetting more profitable because if you know the sports very well, you can really earn good money. but with casino classics, don't expect that you will go home as winner.
