there are some bitcoin lending sites where you can lend your money and get some interest on that money for a specific time. well I tryed them out and found that some times the repayer can scam your money so I have come up with the new money investment system in yobit exchange. basically they let you invest your money like banks and they will use that money and make profit. after that they will pay you some interest for your money. and its better interest RTS than banks at least.
