Late-night candlesticks sometimes feel like a thorn, piercing through the veil of time. I still remember that cramped rental room seven years ago, the screen's light flickering in the darkness. A mainstream public chain's coin shot from 1800 straight up to 2400. I poured all 3000U into it. The moment I pressed confirm, my heartbeat and the chart's trend synchronized in resonance.

Over the next seven days, a floating profit of 6000U made me live on the edge of a cliff in paradise. I turned off the take-profit alerts, and the thought of "sell at 3000" kept replaying in my mind, so much so that even the aroma of friends inviting me to dinner couldn't distract me. Then policy news hit, and the coin's price plummeted back to 1900 within hours.

Watching the profits disappear from the screen, I still fantasized that "mainstream coins will rebound sooner or later." In the end, my account settled at 3000U. That moment, I squatted on the ground, nibbling on cold bread, my throat tightening—I finally understood that no matter how safe the asset, it couldn't compete with the greed worm in people's hearts. I paid this tuition more than once: NFT from 15,000U to 32,000U, refusing to sell, then cutting losses and leaving; during swing trading, I actively deleted stop-loss orders, stubbornly holding until assets were halved.

Only when the wounds were deep enough did I learn three survival rules:

**First Trick: Diversification Keeps a Way Out for Yourself**

35% of the principal goes into cold wallets to store BTC—this is the ballast that carries you through bull and bear markets. 45% invests in mainstream assets like ETH and SOL, firmly avoiding small coins. The remaining 20% is emergency funds, always leaving breathing room without full position. No matter how crazy the market gets, never throw all chips into one gamble.

**Second Trick: Taking Profits is True Wealth**

Floating profit is just a number on the screen; only when it hits your bank card does it become your money. Last year, a coin surged from 1900 to 2500, with a paper profit of 120,000U. I immediately withdrew 42,000U to a fixed deposit. Later, when the coin dropped to 2100, seeing that secured profit, I finally understood—ups and downs are market matters; the certainty lies in your bank account.

**Third Trick: Stop-Loss is About Drawing the Line with Out-of-Control Yourself**

Trigger a 2% loss on a single trade and exit immediately; if monthly drawdown exceeds 5%, enforce a rest. I once believed strongly in "mainstream coins resist declines," until a hard hold resulted in a 3000U loss that woke me up. Now, stop-loss feels as natural as breathing—admitting small mistakes to avoid irreparable disaster.

This market isn't short of miracles; what’s missing is the clarity after crawling out of the deep pit—staying sober, not greedy, not stubborn, not impulsive.
