Is it possible to happened and is there any gambling platform permits that?
None that I know of. Stake recently supported deposit and withdraw in naira but if you deposit in naira, you will only be able to withdraw in naira.
What I also know is that if you are able to deposit a coin on a gambling site and withdraw in another coin, that does not mean you will be able to use it to exchange into your local currency.
Though was thinking this is possible because often time when I gamble and I won, the winning will be displayed to that specific currency I deposited instead of showing on a neutral ground in form of permissable to have it withdrawn in any currency that I wanted.
It would be great for casinos or gambling site to enable this feature to allow gamblers have withdrawal from any currency of their choice and if that must be activated let it be that there will be some wagering requirements to permits them withdraw from other currency of their choice.
I know they can do this and might take a little stress to implement it to their site, maybe just some adjustments or something so, can help improve the entire gambling system.
