myself before investing, I have to make sure what I will invest before because I myself have been cheated by people because my knowledge of investment was very lacking at the time and now I am always careful before investing in crypto, because crypto is also very dangerous in my opinion because it has very large profits and losses that are of the same magnitude, therefore I have to learn carefully before doing an investment with large funds in it.
If you learned finally that people used to cheat you, the best decision for you will be NOT to listen to anyone and explore the market relying on your knowledge and intuition. It will work much better.
