Mioptc is correct in this case. No interest for the moment on FUN tokens.
Never heard of any legit exchange that gives such an APY for BTC, I doubt they will be long in existence with this kind of unrealistic returns. An interest of around 4-5% is much more sustainable in the long term.
Binance is one such exchange offering good APY and of course if you count DEXs as exchanges then you already have Uni/Sushi and yearn and now even new ones like 1inch and plasmaswap all offering double digit APYs, but that's a bit more complicated than FBC.
Nexo I think gives 5% flat, more with other tokens. Which is the equivalent of a centralized exchange?
