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.
Yeah. It seems like this is the most reasonable and obvious explanation for the difficulties with adding payments to BSC in this casino. And you are absolutely right that devs believe that the cryptocurrencies that Roobet.com uses and that have acceptable small fees, such as TRX or DOGE, are enough. LTC is also a pretty convenient cryptocurrency. And of course, cases like those with users who mixed up blockchains are extremely rare.
But in this case, the amount of loss is quite significant and apparently this issue could be resolved somehow. Maybe OP will really try to help the user who made such an annoying mistake.
