You can get up to 60% APY on other cryptocurrencies, not on the BFG tokens (nor the sBFG tokens). To get that, you need to lock in your crypto for 1 year and have done some wagering also. I never profited from these APY's until now, but they might be interesting to check it out as I don't think Betfury will go down in the next years also.
I don't think casino itself will dissapear in a year, but price of token, that's another story alltogether.
I'm not saying BFG token itself is bad or anything, it's just its very succeptible to the market. I've seen tokens of stronger projects go down because of market
it also depends on what you can do with the token and if it has good utility.
besides playing with BFG, AFAIK you can only stake it, but i think it would be much better for the token price in the long run if they added some kind of lottery that uses it imo.
