Right now, you can't buy their tokens as you can only get it when you play on their site.
If you play BTC or TRX, you can get BFG tokens - BFG(BTC) or BFG(TRX) even if you are losing.
So it depends on how much you are spending on their site to get their tokens.
These tokens, will automatically be staked and you can get your dividends accordingly.
They said they have plans to get this listed but the timeline is not yet known, as others have said, they are not in a hurry.
This kind of innovation is very unique honestly I have not seen this implemented or another gambling site has this kind of feature, I stand to be corrected if there's another site with the same feature, even if you lose you win I just noticed my BTG tokens are adding up even if I'm losing, it's excited to play here, and it will not make you feel bad that you are losing because you are still making money through staking, auction and invest box.
