The disadvantage when depositing and playing with Tron is that you get BFG (TRX) subtokens which are less interesting and rewarding than the BFG (BTC) subtokens.
They recently also added ethereum as an option to deposit, but fees are also high unfortunately.
So it depends on which currency you are betting will get the BFG? I thought they were just one BFG token and you will earn stake in all coins. So if you have BFG (BTC) You will only receive dividends in BTC?
