Trading cryptocurrencies is a series of operations as fierce as a tiger, just like holding coins through spot investment, both carrying the risk of losses. Choosing to make quick profits and see wins or losses immediately is actually fine. Some choose to hold coins to give an explanation for the future, which is also perfectly okay. In the short term, it's impossible to tell who is stupid and who is smart. I advise those who often mock others for being stupid not to think they are smarter than anyone else. Ultimately, time will write the answer, but the only thing that can be certain is that those holding chips are definitely the final winners. As for trading contracts, it's purely gambling, and you need to consider whether the few hundred thousand in your hands are enough to fill the坑😇, consider whether you can outplay those big players who often deal in tens of millions. In their dictionary, there is no such thing as "liquidation." And yet, you keep worrying about liquidation every day.
