It is understandable that you feel frustrated and want to change your investments to less risky assets. However, it is important to remember that risk management is more than just changing your investments. It is also important to consider diversifying your investments and managing the amount of risk you take on. For example, you could invest in both USDTZ and other assets such as stocks, bonds, and real estate. This way, you can spread out your risk and have a better chance of seeing a return on your investments. Additionally, you should look into strategies such as dollar-cost averaging and rebalancing your portfolio to help you better manage the risks associated with investing. Ultimately, it is up to you to decide what investments are best for you and your goals, but it is important to remember that risk management is an important part of investing.
