Many people often come to ask how to choose coins and when to buy. My answer is actually very straightforward—the methodology isn't complicated; the key lies in the three words "steady, accurate, aggressive." Many only realize after suffering losses that instead of blindly pondering, it's better to follow this logic, which can save a lot of detours.

First, learn to pick "active coins." After the market opens each day, review the top gainers list and note those with unusual upward movements and obvious abnormality in your watchlist. Simply put, only coins with continuous inflow of funds can potentially lead to decent market movements. Projects that have been stagnant for a long time and are ignored are a waste of time to touch.

Timing is crucial for entry. Keep an eye on the monthly MACD golden cross; this is a real signal that the trend is starting. Instead of betting on oversold rebounds (which is purely luck and very risky), it's better to follow the clear trend, which can double the probability of profit. Add one rule: when the coin price retraces near the 60-day moving average with significantly increased volume, then consider entering. Don’t guess where the bottom is or gamble blindly on the direction; wait patiently for clear signals.

Once in, discipline is essential. Hold your position as long as the trend hasn't broken and support levels remain intact. But once the support line is broken, whether you just bought or have been trapped for a long time, exit immediately—don’t be soft-hearted. The biggest trap here is reluctance to cut losses; hesitation in those few minutes often leads to liquidation. Better to earn less than to drag on and risk a total loss.

Profit-taking should also be done in stages. When gains exceed 30%, halve your position; when reaching 50%, halve again. Don’t expect to ride the entire rally; small profits accumulate over time, and the long-term returns can be more substantial. The final iron law: when the price falls below the 60-day moving average, close all positions, regardless of the situation. This rule has helped me avoid countless market reversals. Being too polite to the market only costs you.
