why do some online casinos have way stricter monthly withdrawal limits?

Been noticing more and more sites lately locking down their monthly withdrawal limits, and some of them seem insanely low. Makes me wonder if it’s always about “player protection” like they say, or if there’s some other angle. I get if the place is tiny and maybe doesn’t have a lot of liquidity, but you’d think with how much some sites advertise, they'd plan for higher traffic and handle bigger withdrawals.

For crypto casinos, it always confuses me even more. The money’s supposed to move faster, and blockchain doesn’t really have old school bank issues, so why act like a regular wire transfer? I can see maybe it’s for their own risk management, or maybe they’re just hanging onto deposits as long as they can. Seems like reliable players would rather know they can get at their winnings without begging support every time.

Anyone else run into this? Does anyone know if there's usually some legit reason for a casino to drop limits so low, or is it more about holding onto customer funds?
