Legal analysis: soliciting friends to invest has caused losses. According to the nature of the contract, both parties should judge according to the obligation characteristics of the agreed rights. Entrustment contract mainly refers to the agreement between the principal and the trustee. Entrustment contracts are divided into paid entrustment and unpaid entrustment. The paid entrustment contract shows that the principal's obligation is to pay remuneration, and the trustee's obligation is to complete the entrusted matters independently. If you simply invite friends to invest without any remuneration or fees, it is a free commission, and the responsibility of the trustee needs to be reduced according to the situation. In addition to this simple form of entrustment contract, there are also some reasons because of foreign exchange pyramid schemes. For example, many foreign exchange platforms can get dividends when they invest, which is likely to attract friends to invest and cause losses.
