$BTC Contract “Three Golden Rules”: protect your profits, cut your losses, and follow the rules.

First, learn how to “put profits in your pocket” before you make money.
After you’re up 10%, immediately set a break-even stop-loss—if it falls back to your cost, you run. Never let profits turn into losses.
Once you reach 20%, at least lock in 10% of the profit; once you reach 30%, lock in 15%.
You don’t have to sell at the very top—just make sure that every time you can leave a little prize behind, and don’t let your account swing like a rollercoaster.

Second, when you lose money, treat it like “severing a warrior’s arm to save the body.”
Before you open a trade, set your stop-loss—for example, if you’re down 15%, cut it right away. No hesitation, no fantasies, no “holding the bag.”

After your stop-loss triggers, the market keeps running up? Don’t slap your thighs in frustration. It only means your entry timing was wrong—but your principal is protected.
Trading allows you to make mistakes, but it never allows one mistake to send you packing.

Third, did it go up after you sold? Then take it back according to the plan.

If you still believe in it, buy back the same amount when it pulls back to the planned price; if it doesn’t pull back and instead keeps running up, then be honest and chase it back too—pay a bit more in fees is better than being sidelined the whole way until you end up regretting it.
But if you buy it back and it gets stopped out again and again—getting slapped in the face repeatedly—then it means the current market isn’t for you. Stop and wait for the next round.
The last hard truth:

In short-term trading, you’re fighting with rules—not fortune-telling.
Fast in and fast out doesn’t mean reckless messing around; chasing hot spots isn’t the same as charging blindly; staying in cash isn’t missing out—if you can consistently earn the share that belongs to you, you are the winner.
Remember: protecting your principal is more important than making money; following the rules is more important than predicting.
