As far as the form of investment is concerned, private equity fund is an investment mode in which many investors' funds are pooled to form independent assets, which are entrusted by the fund custodian and invested by the fund manager in the form of portfolio. It is a kind of investment mode in which interests and risks are shared. Peer-to-peer refers to the lending behavior between people. P2P wealth management companies are equivalent to intermediaries, connecting borrowers and lenders to meet their respective lending needs. Intermediaries generally charge fees from both parties or unilaterally to make a profit or earn a certain spread as a new financial management model. As far as the scope of investors is concerned, private equity funds are generally non-public and the circle is relatively small, but the threshold is not low; While P2P is open to the public, and the initial investment amount is generally 50- 100 yuan, so it can be said that the threshold is very low, and it is very popular among civilians, and the number of people is unlimited. Therefore, P2P has a wider range of investors and is more suitable for ordinary people.
