Hmmm, 6% monthly is a huge money which is not feasible. Otherwise everyone can just put their money and go to sleep. It should be yearly which is understandable. What happens when exchange gets hacked, are the loans backed up by anything!
Earnings are monthly, check out the link below. However, I have no idea about the lost funds, but mostly big exchanges like Binance pay back the stolen money from the cold wallet.
If you are looking for lending why not to try another lending platform like Nexo?
Nexo offers even higher interest, upto 8% on all stable coins. Never heard about the platform? It is probably the biggest crypto lending platform with more than 300 000 active users! So why are you waiting for limited slots on Binance?
Earn 8% interest per year which is significantly higher than traditional bank deposits and alternative investments. Nexo offers you full flexibility by allowing you to add and withdraw funds at any time.
If you are talking about this, it is annual investment, but Binance's offer is a monthly gain of 6%. For more:
