I won't go into the definition of the p2p lending because it is already available in various resource which can be fetched through Google search! Rather, I would tell you about my experiences with it! It is a failed business idea in crypto space! BTCJAM was one of the pioneers of crypto p2p lending which closed down their operations back in 2017 or in 2018 beginning. I had an account and I used to lend to a lot of highly ranked borrowers. Only 90% people defaulted and I received only 10% of my investment back. I would be at least 4 bitcoins richer today if I had avoided this p2p lending business back in 2016 and 2017. It's a flawed business idea because you can't really track down a person in Nigeria from USA for few hundred dollars!
