Online gambling platform can be referred or assumed to represent online casinos in General, this is to say that online casinos that accept only fiat currencies, and those that accept crypto, can all be categorized as online gambling platforms.
But on the other hand, crypto casinos are known to be online gambling casinos that accept cryptocurrencies as a means or medium of deposits and withdrawals..
This two both remain online gambling casinos, but their mode of payments is different and that's all that there is to them.
