Brothers, I'm a newbie and want to ask a question 😳

Is the concept of wealth management only to ensure the increase in the quantity of the currency, but not guarantee the change in the value of the currency?

For example, if I buy wealth management with 1000 ar, I will definitely receive > 1000 ar in returns.

But if the market value of 1 ar is 6 usdt when I buy it, I cannot guarantee what its market value will be when I sell it.

I don't know if my understanding is correct?

Additionally, is wealth management absolutely risk-free (in terms of quantity)?
