If you want to lend btc one option is to use bitfinex. The interest is payed daily. You can get a lot of info about them just by google it but if you have any specific questions, shoot me a PM and I'm glad to assist you. I'm using them for over 8 years now. They were hacked at one point but they have compensated all the customers.
It seems that you been a bit confused. OP doesn't want to lend his BTC through any platform or here but to his friends/ private circle.
