A few things why I think there are not much good online poker gambling sites,
1. Because it is just a niche kind of gambling game. There is not much players looking to play poker to gamble. Since in poker you need to be more than lucky in it, you also need skill. There is a smaller chance to win in poker than in just playing games like dice, if you do not have enough skill.
2. Ultimately related to number 1, is that gambling sites and operators do not profit so much from it since there are not much players and there is really no house edge.
3. Takes so much time to finish a tournament, or even just a single game. This is a factor to consider for both players and the operators. Since most players do not really like to wait too much and the operators do not like to have a long game since it would cost a lot more to run their poker site eating their profits.
I don't thinks , maybe your points are right but IMO I don't think so
1- yeah poker need skills and unskilled players have better chances winning at dice , but that doesn't mean that people don't want to play it
it's fun and games can last kinda long , so players are both gambling and having fun at the same time
2- operators profit way more when it comes to poker as I stated , there is house edge and that's the rake
gambling sites easily make 5-10% of the buy in for tournaments , and they make money from cash games too without taking bankroll risks
in gambling when a player wins 100K he is winning it directly from the casino bankroll , while in poker this profit comes directly from other players
there are many players who are willing to join a good bitcoin poker site , as long as the owrners are trusted , the software is good
we haven't had a single site like that so far , so can't know for sure
3- the time shouldn't be a problem , you can choose the games that suit you like me personally I don't play the tourneys in ACR cause they need a lot of time but other people like that so that's not a factor
at worst case the site can create a game like spin & go in stars , where games last like 5 mins on avg and people can choose the games that suit them
