Just two months ago, a fan commented saying, 'You only know how to go long, not short. What kind of trader are you?' I was deeply triggered. Later, another KOL said that traders who only know how to trade in one direction aren't skilled, and I totally agree with that. Anything you don't know can be learned, as long as you're willing to learn, you can master it. Now, no one says I can't short anymore. Instead, they're saying I haven't failed a single short trade recently and even call me the 'leader of the bears.' This is something worth celebrating. Knowing how to go both long and short makes it much easier to make money in this volatile market. Also, I only trade BTC contracts and don't touch any other coins. I've always considered myself a beginner in contracts trading, and I'm satisfied as long as I improve a little every day. I'm not expecting to get rich from trading contracts—just earning some living expenses is enough for me.
