The swap feature that bc.game is indeed great and I already used it quite some a lot, mainly to exchange some BCD into some other coins.
Yeah the swap feature by Bc.game is the one I love the most in their platform because most casino platforms don't have this feature.
Honestly, the swap feature or the exchange feature is actually helpful. Not just with those specific exchanges that you want to keep whether it's with BCD or any other altcoins that you prefer to gamble with. One use of it is if you want to withdraw and you find BTC withdrawals are quite exhausting and ain't fast, you can exchange into those altcoins you prefer that have a quicker confirmation time so you save the fees and as well as the waiting time.
Stake.com which I think is the most popular casino does not have a feature like this. This kind of swap feature really helps right now to reduce transaction fees. That is the reason why I choose to play on Bc.game; the convenience and cost savings make it a preferable platform for me.
I think that they have but I haven't used that feature yet or there's sort of requirement before a user is able to use that swap feature.
