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.
You have other similar sites, the ones where I played are wink and trustdice... both older than betfury and still around! I still get dividends from wink, I didn't spend so much time and money on trustdice, so dividends from them are too low...anyway their tokens are listed, but I don't think they are worth buying if you are not planning to stake them for a longer period, and of course to add more (with buying or playing/mining) whenever you can (to maintain the dividend payouts).
To not spam Betfury topic with other casinos, but you have similar casinos on other blockchains, you can try to search more about them, and you will find it...but I am not sure they can be trusted!
Getting on the market has pros & cons, if you wish to learn more about it check sites mentioned above and what's happening with their tokens and make your own conclusions! For now, I think it's better for us to stay as it is, the only way to get to BFG tokens is playing!
