I have always advised everyone not to trade contracts, not to trade contracts. Since I shorted Eth in 2021 and lost 3000U, I basically haven't touched it. Last year, I played a little with 10 - 30U, and still lost more than I gained. At the beginning of this month, I opened a coin-based 2x leverage position #LINK🔥🔥🔥 , and after a month, I basically didn't earn anything, and even lost a little. Last night, when it went up, I closed my position. I still have to worry about being liquidated at any moment, and I can't even sleep well at night, which seriously affects my life. Stay away from contracts; getting rich is always a small probability, but giving up the dream of this probability falling on oneself, it’s better to play spot trading steadily.
