For instance; If i deposit Cryptocurrency and gamble and with I win can i be able to withdraw my winning through NGN?
Is it possible to happened and is there any gambling platform permits that?
Like others have said, these casino systems are designed in such a way that you will only be able to make withdrawal through the same way you deposited.. I used to also wonder like you why this was done this way, but ufs as simple as so that the players might not make a fool out of the convert system. If you have heard of people buying on platforms at cheap rates and selling at higher rates somewhere else. So these casino tries to avoid these case scenario where exchange rates are used to make profits.
some casinos allow it
not sure if in size but for a couple thousands you will probably have no problem, including some that have no KYC
maybe would be usefull for users to share a list here with all the places you can do that...
