I believe online poker will survive tighter regulations, but in a different form than in the past.
Regulation fragments player pools, which hurts traffic and game quality, but demand doesn’t disappear. Where players want to play, operators will always find a way whether through regulated markets, shared liquidity, crypto-based platforms, or private/club models.
Poker has already survived major shocks (Black Friday, segregated markets, HUD bans), and it keeps adapting.
In 10 years it may not be as open or easy as before, but online poker isn’t going anywhere.
