What is the average return on Prosper?

Could you please elaborate on the average return rate for investments made through Prosper? I'm curious to know if it's a viable option for generating a steady income, and how it compares to other peer-to-peer lending platforms or traditional investment avenues. Additionally, are there any specific factors that influence the return rate, such as the creditworthiness of borrowers or the duration of the loan? Understanding these details would help me make an informed decision about potentially investing in Prosper.
