The risk of national debt is small. National debt is a bond issued by the state as the main body. It has the highest credit and is recognized as the safest investment tool. Generally called "risk-free rate of return". Although there is no direct commitment to protect capital and interest, there is basically no possibility of loss.

Compared with the national debt, the fund is more risky, but less risky than the stock. The fund mainly invests in a basket of stocks, and the more investment targets, the more stable it is.
