be gambling addicted, maybe sometimes not be able to place a bet because the deposit had not been completely arrived/credited (sluggish blockchain / number of confirmations)
If that gets to become a problem, then such gambling sites can go with LN technology for scaling their bets. A channel could be created between the user and site and he can send the funds through the channel faster than ordinary fiat gambling sites. It would be required to have a confirmation only when you are closing the channel. Possibly before placing a bet either we should have left at least minimum btc in the wallet or should backup our funds prior for faster bet placements.
We need to remember that gambling is getting slowly integrated with blockchain technology so that the bets can be checked through smart contracts and payments are issued at a faster rate. iGaming sectors are growing at a rapid phase which will serve as a competitor for manual gambling sites.
And I think that the credit goes to blochchian and bitcoin which make it possible for gambling throughout the world to become integrated. No doubt that in previous days it was difficult to play gambling because of exchanges of currencies not now bitcoin make it more easy to visit any gambling site throughout the world and play gambling there without converting your currency into any other currency.
