I guess you are referring to the sports book section because the casino games are all using usd as the unit no matter what cryptocoins we use while playing. For the sports book is not the same indeed, lets say our balance is in TRX then we have to specify the bet in TRX.
At the end we will have to exchange cryptocurrency to fiat currency for using and spending. See how exchanges deploy trading pairs for users, BTC/ USDT, BTC/ USD and so on, they are pairs of Bitcoin and cryptocurrencies with fiat currencies.
Even we don't cash out, don't convert BTC or cryptocurrencies, the equal value of it to a fiat currency, is helpful for us to know how much we have in our portfolio or account.
The best option is to deposit using USDT imo so it will be simpler for you to bet using fiat numbers without calculating if you are using other coins. For sure, it will be nice if fortunejack can provide an option to bet with fiat number (usd) in sports like what we can do it their casino games.
Your recommendation, in my understanding, is like users can bet with TRX, but on the screen, the platform will give an equal value in $USDT or $USD for user, but the cryptocurrency used for bet is still TRX.
Is it your recommendation here?
