Actually what is called an instant withdrawal is a withdrawal that has a very fast process and even takes only a few seconds to 1 minute to successfully enter the crypto wallet that is owned by the user.
If they make a withdrawal with 1 to 3 days then it cannot be said to be an instant withdrawal, in fact it is more a manual withdrawal made by the casino team so it takes longer.
Maybe this kind of thing can be a concern for the casino team to be able to develop their withdrawal feature, as has been said on the start page, namely instant withdrawal.
The ease of each withdrawal or deposit process is one of the services that is the main factor for customers to be comfortable and loyal to crypto casinos.
