It's fairly straightforward actually, make sure to have an account on Betfury, you can do this by simply logging into it with metamask. After that get funds on the Binance Smart Chain, buy BFG on the Biswap dex and once you have it deposit the BFG into your Betfury account. Once on there (you don't control the keys anymore) it will automatically start generating daily income which can be claimed in either more BFG or in the separate coins.

Good Luck!
