This coin previously reached over $4 but I didn't take profits in time and was later stopped out. Today it suddenly surged again, which is indeed a bit regrettable. However, this loss made me realize that the key to trading altcoins is to stick to your strategy and not be scared by short-term fluctuations. My current approach is to select a few promising small-cap coins, open multiple positions, preferably covering the fee costs, and then hold patiently. As long as I control the risk of liquidation, the market makers can manipulate the price up and down without fear, and earning fees will gradually recover the capital. Setting stop-losses can actually make it easier to be wiped out. Of course, the current price is definitely not a good entry point. I'll look at other targets. I've been holding POLYX for over ten days; it appears to be in a loss on the surface, but including fee income, I've already broken even. In such a restless market, this steady approach is actually the most suitable for me.
