Smooth game (only tried demo), I think provably fair blackjack is already existing in a few casinos, but I can see that your odds are among the best: 3/2 is quite rare for crypto blackjack in my experience, and hitting on soft 17. I would say that you need to expand to survive though. Interaction is key, maybe build in some kind of tourney or PvP BJ function with chat.

Welcome to the community, hope you enjoy your stay.
