Gambling and pofit in the same sentence is something you dont here everyday but certain games allow you to make some money like poker, but when its you against the house that should be for fun because it never ends well as the house always wins.
that's a shitty mindset to go in with in my opinion. if you're playing for fun, you're playing with the idea that, in the end, you don't care that you lose your money. even if i do lose, i can let it go, of course, but im not playing like i have no regard for the money i put into the game. edge or not, ill try to win out to the best of my ability, and if i lose, oh well. the point stands, however; edge or not, you've got a chance to multiply the money you came in with, and a fairly good chance at that. think of the edge as the houses' fee for hosting the game, and just play.
Making some profit is hard in the long run, but even if you want to get something from gambling, the first thing you must do is to have a proper bankroll management. I saw a lot of people lose all of their money because of sudden impulse to go all in, never do that if you want to make gambling profitable.
bankroll management does nothing for you in the long run given the house edge. the more rolls you play, the bigger potential effect the house edge can have on your rolls overall. if anything, just a simple 2x roll all in might give you your simplest ad most effective way of doubling your deposit.
