gambling never be profitable in long term.Short term you can be profitable if you had good luck but long term 100% chance you will lose all your investment.If you are enough lucky on gambling then this is okay to you but I think 99% people are looser on gambling.play for fun and put how much money you can effort.continuously make 50-100 $ a day just impossible on gambling.
like I've said, define gambling. Poker is technicaly played in a casino, poker is gambling thus "casino" gambling can be long term profitable.
It can be but it requires a lot of patience, that's for sure. If you think about it, if you are requiring yourself to be patient in your games, you can practically always be in the profit side, and play slowly and keep track of your money and plan for the future if you will withdraw or not, something like that.
Yeah.. but my point is some gambling games have no chance of long term profit cos they will always been in the houses favour with fixed and predictable odds like roulette, but with poker you win from other people playing worse than you in the long run.
that's because in poker, you're playing against the other players instead of the house, and the casino just takes a rake of the pot for hosting the game and whatnot. even if the game might be profitable for the player, the casino still makes a profit.
Also, you should define gambling before asking this question.
There is +ev gambling,
and there is -ev gambling.
gambling is gambling, games where you risk your money for a chance to either win or lose. +/- EV are just two scenarios where you can generally expect a win or loss in the long run given a statistically ideal outcome. we dont need to be overly analytical and subdivide gambling into niche outcomes / cases / scenarios.
Theoretically it is possible. For a while things may work out for you. But in the end the house edge will win, it always does. There is no way to make profit from gambling in the long run, you may try your luck at it for a short while and then if you get any profits at all, just bag it and don't be greedy, run far away from gambling. This is the only way to profit from gambling. If you don't stop gambling, and it gets addicting to you, you will keep on investing all your saving into it to try and get a good profit but in the end you will lose every single Satoshi to house edge.
not always. +EV only means in a statistically perfect situation, the house will be expected to win by the house edge percentage over the long run. statistics doesnt say so, but it is possible to beat the house in the long run. its just unlikely.
because gambling its about skill and luck. without this factor gambling cannot be profitable for long term.
