This is reasonable because as the Bitcoin price is gets higher, of course transaction cost gets higher too. And its just right that its an advantage that you can too directly play the earned satoshis to selected gambling sites. However true, there's really a big change truly after the bitcoin halving. Just like how temperature higher, transaction fees gets higher too.
I think there are only few people who gets paid through their crypto casino account, I only know few campaigns as most of them paid directly to the users bitcoin address. However, I think it's not too relevant now because bitcoin transaction fees are back to its normal, at least we can transact now with $2 or below, unlike in the past few days where it's really high that it's almost impossible for us to take our money out from our wallet.
