Xiao Afu never uses TG, any Xiao Afu on TG is fake, and he never proactively contacts any friends to introduce me to buying and selling U orders, because the introducer is easily deceived by the triangle, and Xiao Afu will not ask anyone to borrow money from U. Trading on the exchange is very convenient. Anything that requires your introduction is problematic and you want to cheat your money. Don't even think about being an intermediary to earn some introduction fees. OTC trading is deep and can easily make you an accomplice to criminals.
