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?
Just to give a couple of examples:
1- Bexplus is one of the Wallets that offer good returns just for having the BTCs stored there, from 3% to 21% previously it was up to 30% here is an updated table of its APYs: https: // www. bexplus.com/es/activity/btc_wallet.
Another would be Nexo with 6% APY.
And just for putting a casino you could name BC.game that offers 5% APY in any crypto with no minimums.
But Personally, I only have my BTCs in FreeBitco.in for years and in addition to the ease and practicality you do not need KYC without a doubt it is one of the best wallets where to save BTC to earn passively obtaining benefits without risking.
