I it not about having options only.
It is about making it fast and without problems. Preferably decentralized.
freebitco.in for example is rarely doing manual inspections and every other withdrawal request is fully automated. If you have a rock solid, hack-free casino you can do this too. Otherwise you'll have to manually check almost every withdrawal request which is going to frustrate the players and then naturally they will leave this casino.
That's right. The speed of withdrawals also matters. Due to the fact that we gamble on crypto gambling sites, we are used to withdrawals being processed in a short period of time, so any delay could be a cause for concern or an unnecessary panic, and that is definitely not a good situation to find yourself in. After all, crypto gambling sites are a business, too, so they do not want customers leaving due to certain concerns. So you want to make the withdrawals fast, right?
By the way, when a casino puts restrictions on withdrawing money from your account, that means you are at their mercy, and therefore no longer in control. You no longer have the option to use your money whenever you want and how you want it. And freedom of choice is a key factor when it comes to something as important as money.
They are just taking advantage to us and try to get control with how we choose to spend our winnings upon withdrawal, seems like they just want us to deposit and deposit without getting the benefit to choose what we wanted about it or play games after winning huge so that they can have a chance that the money will be back to them.
Nevertheless, any gambler will agree that a reputable casino won't give the users a hard time withdrawing their funds/winnings because they can also see if a deposit has been made and the user played a game to explain the big funds being requested to withdraw.
Putting more restrictions and give a hard time to the users will just a push factor to lose a client, for good.
