The operation with $TNSR completely showed me what madness is. I originally planned to run after making a profit of 20 points, but after hesitating for a few seconds, a long wick candle directly pumped, and my profits evaporated instantly. At that time, I was still fantasizing about whether I could catch a big swing trading, but now thinking about it, it was simply naive. This kind of coin that jumps up and down has a ridiculous volatility and is really not suitable for any long term strategy. In the future, when encountering such varieties, it's best to lock in profits first; greed will only send back the cooked duck. Take profit is always the hardest lesson.
