The hardest part of this project will be to transition people from Pokerstars, which also means people will have to transition from fiat to Bitcoin.
Although if I understand well, people will still be able to use fiat to fund their hobby.
Again, getting the coding work done is only the tip of the iceberg, it will take much more to get a decent user base.
Its much easier getting the poker community into bitcoin then it is getting the poker community away from pokerstars and any other sites. Poker players go were the good games are at. Using bitcoin wont matter much to them its just like exchanging to casino chips. Generally poker players online are smarter than average and understand computers better than average.
