I have staked around 4000 BFG tokens in total and have already quite a few times withdrawed money (always small amounts) and has never been asked to submit KYC. Probably if the amounts would be much higher, I might be asked to do it.
4000 BFG is not a big value in USD at the current price it is around $ 50, and if you say you have withdrawn several times even with a small amount I suspect that your investment in BFG has provided profit or BEP, if yes this makes me interested to also start doing BFG staking especially if betfury absolutely will never ask for KYC.
Doesn't want to FUD or change your mind, but there is no any single gambling token which "success". Let say, Bitdice with their CSNO, Betking with BKB, Freebitcoin with FUN (although i'm not too sure about this one). All of those token are dead rn, not traded or just have low volume. If you are going to stake, make sure you have calculated everything, especially probability if the token price dropped, does your staking reward can cover that. I also see the BFG chart still on bearish now
