Their are cryptocurrency sites that allow you to earn interest on your bitcoin and other cryptocurrencies without KYC/AML.
Most of them are cryptocurrency casinos that allow investment into the sites bankroll.
Freebitco.in allows the user to earn 4.08% APY for any balance of bitcoin above 30,000 satoshis.
Bustabit.com allows a user to invest into the sites bankroll at a cost of a dilution fee of 2%. Example: invest 1 bitcoin into bankroll you automatically lose 0.02 bitcoin. It appears though that the sites ROI has been around 20-30% a year with the volume of bitcoin wagered.

bybit.com has a rewards program of up to a free 90 USD to trade after initial deposits. This is a crypto exchange.
