I know coinflex.com's ~7% interest paying stablecoin (available on SLP) sounds too good to be true but after looking into it in more detail I have to say the company seems quite legit. Roger Ver seems to be one of the investors and in general I got a solid impression of the team behind the exchange.
You can sign up without KYC and withdraw up to $10000 with KYC level 1 (which is basically no kyc).
I'm in no way affiliated to them so do your own research. But an interest paying stablecoin on SLP (that pays actual on chain transactions straight to your wallet 3 times a day!) could be quite big
