Is it safe to dig for treasure?

On June+10 this year, I debugged three kinds of mobile phone wealth management products, namely, treasure digging, Yingying wealth management and PP wealth management. After purchasing the wealth management products for the first time (the annualized income is about 8%, and the novice may have 10%), the principal and interest were indeed returned on schedule (later, my wife found out and criticized me for hiding the private money, so I didn't buy any more ...). For the simplicity of the operation of the APP, I personally recommend Yingying Wealth Management; For the comprehensive function of the system, I personally recommend Digging Treasure (Digging Wealth Manager). Because the mobile phone interface of PP financial management is often unable to log in, it is more troublesome to transfer funds, so it is not recommended. As far as the treasure itself is concerned, I personally think it is safe.
