Does new song technology hang up to make money?

Yes, but it is not recommended. There is no such thing as a free lunch, and the risks outweigh the benefits. Hanging up to make money is a scam and one of the forms of online fraud. Usually simple, fast and risk-free as bait to attract people to participate. This kind of scam usually promises high returns, but it has not been realized, and may even steal users' personal information or funds.
