Stop hyping "Moving Averages + MACD must-win" already. I've seen too many newcomers in the crypto space study candlestick charts to textbook perfection, and when it comes to real trading, they become overly confident—"I invested 50,000 and predicted everything perfectly." So what happened? Bitcoin suddenly plunged with a big red candle, and that calmness from before instantly vanished—either scared out at the floor price or impulsively going all-in to buy the dip. In the end, they blame the market for "liquidity hunting" and shift the responsibility outward.

Having been involved in the crypto market for 8 years, I responsibly tell you: the secret to position management isn't about "how much you invest," but about "how much volatility you can withstand without fear." This has nothing to do with how much technical analysis you've learned. Frankly, a reasonable position size is like installing a "pressure relief valve" for your mindset.
Take last year's Bitcoin correction as an example. It dropped from 120,000 to 80,000. Two people I know faced completely different outcomes.
One took a full position with leverage, eyes glued to the screen every day, still debating in the group at 3 a.m. whether to cut or hold. He ended up cutting at 78,000 and ran, only to see the market rebound above 90,000. That feeling of being hit in the thigh—imagine it yourself.
And what about the second person? He entered with a small position, only using 30% of his funds. During the decline, he ate, slept, and stayed calm—because he knew that even if it fell below 70,000, the loss was within his acceptable range. When the rebound trend stabilized, he added to his position gradually, and in the end, he even made a profit.
The most common mistake among beginners is "treating position size as just a number." The correct approach should be "allocating positions based on your psychological bottom line." My simple advice: never invest more than 30% of your total funds in your first position.
