Bonuses/promos play a role for me, I have minimal interest in sticking to casinos with no deposit bonuses or promotions ongoing and will go elsewhere to seek them out. Slow cashouts/cpncerns about solvency etc will make me never go back to a casino when I know my money is likely safer elsewhere. If you can't pay out 5 figures for a legit confirmed win within days thats concerning to me.
What is the big issue with delaying/saving bonuses and how is it abuse? Is it a way to get around a max cashout cap or something playing the bonuses after a withdraw+small deposit then trying to cashout again etc.
