Gambling using fake money will have no responsibility in every betting session because the fake money that is bet can be added again and refilled,
Well, its credit is zero and there's no value on it so obviously there's really no need to be responsible upon using it as it's a feature of the casino where it can be found.
I think playing in fake money mode will not meet real players at the betting table, but we bet with bots and play the game so boring that it wastes time and energy.
It's not your concern to meet real players with the usage of play money. The purpose of having it is to try the games and have the experience felt despite you're not using actual money for it.
