For those trading small-cap coins, staying up late to monitor the market is really crucial. Without notice, your holdings can become liquidity pools for big players — this is no joke. Small coins that seem to have trading volume often have very fragile liquidity depth. Once faced with concentrated selling pressure or main force accumulation, retail investors are easily trapped. So instead of sacrificing sleep, it's better to manage risks in advance — set proper stop-loss levels, avoid excessive leverage, and regularly check your portfolio structure. The crypto world offers many opportunities, but there are also many traps. Protecting your principal is the hard truth for long-term trading.
