It is always good to gamble with different coins.
Some users may have a high amount of Tron and may want to gamble with Tron.
Personally I see no much difference gambling with different coins, and I always prefer BTC myself.
Gamble in a different coins is a great choices of the gamblers for comfortabllity and availability of the player holding coins. But your cirrect I also prefer ti use btc in my gambling games.
Well, I'm not a big fan of TRX but it has
low TX-fees, confirmation times and offers smart-contracts.
So it's quite good for Gambling-DApps and as you pay for each bet and if you win you'll receive it directly to your wallet, it requires less trust than the usual "deposit/withdraw-system".
It might be a good idea updating the OP and title from TRONbet to WINk (@Distinctin)
