$ETH Last night, while reviewing trading data, I took a half-pack cigarette break in the office. A follower in a trading live stream chat was cheering— 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 me do the math: assume five consecutive winning Ethereum trades, each earning 100 points, with a $1,000 capital, it could grow to $3,000. Sounds fantastic. But what if I recklessly leverage and lose 20 points on a single trade? The account is cut in half. Two consecutive losses of 40 points? The lights go out.

A 100-point profit can't withstand a 40-point loss. This isn't scientific trading; it's gambling disguised with a high win rate.

I have to say it: fixed position sizing! No more all-in! Any gambler mentality doesn't 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 addresses two most counterintuitive issues in trading: emotional position management and the lack of discipline in profit reinvestment. Embedding growth logic into smart contracts, in a way, replaces human judgment in decision-making.
