Hey bud, even though there is already a campaign for their promotions that doesn't mean that they will get players as soon as they started this kind of campaigns. Besides, we already have countless of gambling sites where we can play poker, not to mention almost all of these gambling sites are PROBABLY FAIR means 50-50... If they're about to increase the percentage of winnings only from the startbefore they set it to PROBABLY FAIR, they might be able to get players unexpectedly. This will take time, for the reason most gamblers just stay on their trusted sites.
Let's just hope they can get enough attention.
First of all you need to differentiate between PROVABLY and PROBABLY, both sounds similar but has different meaning.
Secondly if you are referring to PROVABLY FAIR system, it is not about your winning chance. You say provably fair = 50-50, so how about a game that if provably fair but has low odds? Does it make senses for you to connect provably fair system with winning chance?
Last but not least, countless gambling sites where you can play poker? You are so exaggerated for this, the number of bitcoin poker sites is not that much. There are some existing sites indeed, but it does not mean that new sites has no chances to compete with the older sites.
