High-volatility cryptocurrencies fluctuate rapidly, making risk management crucial. When encountering such coins experiencing another surge, some traders choose to reduce their positions on the rise while increasing margin to hedge their risk—seemingly able to improve their operation space by 30u. But in practice? Instead of making a profit, this trade resulted in a loss of 1000-2000 yuan. It sounds heartbreaking, but it highlights a real issue: relying solely on leverage to pursue gains often falls into a vicious cycle of increasing costs. Traders need to reassess their position sizing and risk control strategies rather than blindly adding more.
