Last night, while reviewing trading data, I smoked half a pack of cigarettes in the office. A follower in a trading live room was cheering in the group— they made money following the trades. But I felt a chill down my spine.

The problem is clear: the precise 20-point stop-loss gave everyone confidence, but inadvertently opened a dangerous door. Let’s do the math with a calculator: suppose you win 5 consecutive ETH trades, earning 100 points each time, with a $1,000 capital growing to $3,000. Sounds fantastic. But what if you recklessly leverage and lose a single trade by 20 points? The account is cut in half. Two consecutive losses of 40 points? The lights go out.

A 100-point profit cannot withstand a 40-point loss. This is not scientific trading; it’s gambling disguised with a high win rate.

I have to say it: fixed position sizing! No to all-in bets! Any gambler mentality does not belong in a trading system.

After some painful reflection, I started looking for solutions. How can we, from a mechanism perspective, help ourselves and those who trust us to completely lock down the impulse to "double down aggressively"? How to build a more robust asset growth framework outside of trading that can automatically enforce discipline?

In the end, my attention focused on DeFi strategy vaults. What’s most attractive isn’t low-slippage cross-chain swaps, but the "auto-compounding strategy vault" mechanism. It precisely solves two most counterintuitive issues in trading: emotional position management and the discipline gap in profit reinvestment. Embedding growth logic into smart contracts, in a way, is like replacing human judgment with automated decision-making.
