WSOP Only offered in three states. Is he going to compete against WSOP, the most established name in those markets? I see small player pools on sites in US states, so his site has 0% chance to succeed in US.

Good luck with trying to compete against PS in international markets where PS has to deal with so many different regulations in each country. He will need millions to pay legal and regulatory fees before he makes his first $ in rake. This is going to end badly. Since most US players like myself that would try his site, will never have the option to play on his site.

Any site needs to have any easy safe option for players to deposit $. Most sites seem to resort to dealing with shady payment processors since legit ones don't want to touch gambling sites. Getting his software working after two years will be the easiest hurdle he faces.
