By the way, if I were the devs of this casino, I would most likely try to figure out how difficult it is to add this blockchain and payments to BSC.
And by the way, this would probably at least slightly, but still increase the number of clients of this casino, especially if we take into account the relatively cheap payments in this cryptocurrency in terms of commissions. And the rather serious distribution of this cryptocurrency in general in the general world of cryptocurrencies.
So I would like to know how profitable/or costly it is for the casino to further develop their payment systems.
Because of Binance domination in cryptocurrency industry, their competitors like centralized exchanges, have policies against Binance and Binance Smart Chain BSC. They don't want to automatically give free advertisement and listing for tokens on BSC, or listing fees with BSC tokens can be more expensive than ERC20 tokens or other blockchains.
I of course can not say about reasons why Roobet are against BSC listings but they have reasons for it, and fortunately nowadays there are many chains, not only BSC, so it's not big problem for users.
