I have lost a lot in the cryptocurrency world in my entire career, but I have never lost as much as you, and I never imagined that I would lose 300k. However, the loss I have suffered is not small for me, considering my position, although some long-term investments are currently recovering.
Moreover, I think many people can learn a lot from reading this topic that you should never invest in trading with a large amount of funds. First, you need to have knowledge and adopt a proper plan, then the amount that you can afford to lose can be invested in trading or cryptocurrency.
