Right now it's more practical for me to gamble with stablecoin, since Stake is paying the signature campaign through Tether currency. If I have to convert it into Bitcoin or fiat in order to gamble, it means I will be wasting some money through taxes which can be completely avoided if I just use the USDT currency. But some time ago, when they were paying through BTC currency, I prefered using Bitcoin to gamble for the same reasons stated above.

If I had to deposit money at the casino to play, I would choose Bitcoin, though. It's more convenient when playing at online casinos when compared to fiat currency, which is heavily traceable and taxable by local regulators.
