I am wrong if you think from the casino side. But If you think from the user side. Users will get benefitted from the exchanger.
Suppose I have $50 In ETH. I had a chance to lose it if I play. I am happy with $50 and I want to withdraw it.
But I can't withdraw just because the Minimum Withdraw limit is $125 In ETH. So, If they had an exchanger, I am willing to pay 5-10% exchange fees to convert it from ETH to BNB. Then get it into my wallet.
I think you got my point. I am thinking from the user end. Not From the Casino side.
The worst part is that we have to do something like that in order to withdraw our money. I had some ETH in here back in the day, it was a very very small amount, like 9 dollars or something like that I believe, and I couldn't withdraw it because it was under the minimum withdrawal threshold and that's why I had to keep gambling with it and obviously I ended up losing it all.
That is a proof that we need to have some lesser minimum withdrawal level and a lower fee, or at least help it with some swaps so that we could turn it into something else and make a profit there. In any other case I would be supporting the casino to not have an exchange because they are not forced to, however these days the fees of moving money in and out is a lot, so an exchange could be awesome, it would allow people to do whatever they would like to without fear of losing it.
