#ETH巨鲸增持 has been trading contracts for years, and I've figured out a few survival rules—sharing them for friends still finding their way.

First, let's talk about profit protection. Is your position floating at over 10% profit? Congrats, but don’t get cocky. If it pulls back close to your entry price, get out—don’t hesitate. When I hit a 20% gain, I set a rule for myself: at minimum, I take away 10% profit. Unless you’re absolutely sure you’ve found the local top, let the profits run a bit longer. Up 30%? Then 15% is my bottom line. The benefit of this approach is, even if you have no clue where the peak is, your profits will keep compounding upwards.

Loss management is even more ruthless. My personal rule is to cut the position immediately at -15%, no excuses. Some think 15% is too wide—you can adjust it, but you must have a line in the sand. If it bounces back afterwards? That just means the trade shouldn’t have been taken in the first place; the entry was wrong, and you had to pay that price. Always set your stop loss before entering a trade—this isn’t a suggestion, it’s essential for survival.

Here’s a counterintuitive move: after selling, if the price pulls back and you’re still bullish, buy back in at your original position size. For example, you exit a certain altcoin, it drops 8%, and you still like the outlook—just buy back in. Your coin count stays the same, but you pocket the cash difference. If it doesn’t drop much and you don’t buy back, but then it rallies back to your sell point—buy back in unconditionally. You might waste a bit on fees, but that’s better than missing the next move. This works even better paired with stop-losses: buy back if it returns to your price, stop out if it drops further. If you find a certain asset repeatedly triggering this cycle, it’s probably time to pick a different one.

For mainstream coins like $BTC and $ETH , short-term trading is about discipline, not gut feeling. Quick in and out ≠ mindless high-frequency trading; chasing hot trends ≠ buying whatever you see; taking profits isn’t cowardly. The lowest and highest prices? Forget about them—they’re for admiring others, not something you can actually capture.
