We live in a material world and the cryptocurrency market also obeys its general laws. The law of conservation of energy also works here. Therefore, cryptocurrency cannot provide profit to everyone. If you made a profit, then someone else suffered a loss. Plus, we know that prices in this market are very unpredictable. Someone takes risks and makes big profits, while someone takes precautions, but at the same time has losses. I am sure that each of us has both positive and negative experiences with cryptocurrency. It is important not to focus on the negative.
