ndumm and Shuffle admins, a mere suggestion. Because of the current network congestion happening in the Bitcoin network caused by Ordinals/BRC-20, may I suggest that the casino consider accepting Bitcoin deposits/withdrawals through the Lightning Network? I believe it could also be an opportunity to promote Lightning as an alternative and widen your network of users as well.
Perhaps giving free-spins/bonuses for every deposit through Lightning might encourage Bitcoiners to open a new path/method to use Bitcoin?
Just use Altcoins that has cheap fee and fast transaction confirmation like Tron, BSC and many more instead of using LN since you will still need to convert your Bitcoin to LN in able to deposit on it. Besides LN is still not popular among gamblers as an alternative to cut transaction fee compared on using altcoins.
Why not accept both the Lightning Network and altcoins? The more choices for deposit methods, the better for the casino.
¯\_(ツ)_/¯
Plus it was a mere suggestion. If the casino evaluates that it will be more work but with less benefit, then that's OK.
I believe having a built-in exchange is more helpful to have a temporary solution over transaction fee since gambler can send directly Bitcoin to Casino and then just convert it to altcoin on the casino exchange to save fee for withdrawal.
Although that would be a very good feature for casinos, that will require them to apply for different licenses because they would start functioning as an exchange.
What casinos can probably do is, also allow Bitcoin users to have a choice of withdrawing through on-chain or Lightning since there was no currency conversion.
