Friends with limited funds, don't bother with flashy operations. Instead of studying complex quantitative models, master a set of basic and most resilient trading logic that the market can't easily beat.

**Choose a Coin and Watch One Signal**

The daily MACD golden cross, especially when it forms above the zero line, is the most reliable entry point. Don't be overwhelmed by a flood of news; technical signals are always more honest than public opinion.

**Trade with Only One Line**

The moving average. That's it. If the price stays above it, hold; if it breaks below, exit immediately. Don't hope for a rebound, don't make up stories—rules are rules.

**Two Key Points for Entry and Exit**

For entry, wait until the price breaks through the moving average with volume increasing simultaneously—then go all in.

For exit, it's clearer: when gains reach 40%, reduce one-third; at 80%, sell another third. Once it falls below the moving average, clear out the remaining third as well.

**Stop Loss Is Not Negotiable**

If the closing price falls below the moving average, leave at the next open. A moment of luck might wipe out all your previous profits. No rush if you miss the move; wait until it stabilizes above the moving average before re-entering.

**To Sum Up**

This method isn't very clever, even a bit stupid. But it's this simple approach that’s easiest to stick to and least likely to be eliminated by the market. Control your position size, stick to discipline, and every market wave can be bitten into. Don't regret missing a certain rally—opportunities are everywhere, it all depends on your execution.
