If we proceed from the fact that the development of the casino should make it as easy as possible for users to freely play, deposit and, of course, withdraw money to their account, then I think that it would be ideal if the casino consists of "three buttons".
1. By pressing a button or an icon in a mobile phone, wrote the amount - that's it, the money is on deposit.
2. I chose a game, placed a bet, won ... well, or lost .
3. Pressed the button - once, the winnings are on your account....
And no extra troubles.
Here, in my opinion, where it should be striving, developing gambling services.
But this is still, of course, just an ideal dream.
