I would love to know, which approach works better for casinos to increase their revenue and retain more customers? I feel like casinos that pay withdrawal fees out of their pocket have more loyal customers and their customers also deposit more money than those who don't pay user's withdrawal fees. Is there any statistics that either prove or disagree with my opinion? Is any casino representative willing to speak about it? It is a nice topic to discuss.
I am certainly feel attracted if I discover some casino which would cover my withdrawal fees, but also we need to give some further analysis to why a casino would do it and whether it is worth judging a casino only because such feature. It could be something being used by low liquidity/small casinos to attract more gamblers, but they do not actually have time proven reputation or much money to cover big wins by their gamblers if in the case someone of them hit a jackpot.
I don't mind to pay for my withdrawals, as long as they are fair and match the average fee with is needed to carry out a transaction of each one of the coins the casino supports. It makes sense to pay half dollar for a Bitcoin withdrawal if the network is not busy and the meempool is almost empty, but it does not make any sense having to pay the same to push a Litecoin transaction through. Casinos are not supposed to profit from transaction withdrawals.
