There are no significant drawbacks when it comes to the API, as some cryptocurrency mixers in the market utilize Jambler.io as a third-party API.
Yes, I'm familiar with Jambler.io and that's why we all should understand that if a mixer uses the same API then that doesn't means that it's the same mixer. Although things might look same for RoyalMix and Jokermix but they are two different mixers if I'm not wrong.
Those of us active in gambling can relate to this as well, when it comes to sports betting and slot games, there are alot of game providers, this game providers and make their games accessible to several casinos, they act as a third party to the gamblers who play such games on the casino, and one can play exactly same game on different casinos, and that does not mean that those casinos where that Same game Is listed are the same.
This is exactly the same way I understand jambler.io to be, it's like a power house for several mixers and uses their API to provide services to their prospective customers.
By the way, a warm welcome to the forum., hope we are gonna see some promotions soon so users who are not really active on this thread can learn about this mixer as well.
