Everyone involved in the crypto market has these concerns:

How to choose coins?

When to buy and sell?

Answering these questions isn't as complicated as it seems. Three core principles: rigorous logic, rhythm awareness, and discipline above all. Using this system, you can avoid most of the traps in the market.

**Finding Coins with Vitality**

When the market opens each day, don’t rush to monitor every move. First, look at the top gainers over the past two weeks, focusing on those with suddenly increased trading volume. Assets with genuine capital participation offer real trading opportunities; coins that remain stagnant are not worth wasting energy on.

**Monthly Chart Determines the Big Direction**

Daily K-line fluctuations are mostly market noise; the true trend is seen on the monthly chart. When the monthly MACD shows a bullish crossover, it’s a signal that a major trend is starting. If you get the direction right, you profit from the trend; if not, no matter how hard you try, it’s just wasted effort.

**60-Day Moving Average Is the Key Support**

Once the big trend is established, switch to the daily K-line chart. The most crucial entry strategy is here:

Wait for the price to retrace near the 60-day moving average, confirm stabilization, and see trading volume increase accordingly. Building a position at this level means a relatively low cost and peace of mind. The optimal entry point is when the K-line confirms the retracement.

**Breakouts Are Exit Points—No Fantasies**

This is the most testing part of execution:

Once the price falls below the 60-day moving average, regardless of whether your account shows profit or loss, you must exit decisively. Protecting your principal always comes first. Only with remaining chips can you participate in the next opportunity.

**Profit in Stages, Secure Gains**

When floating profits reach 30%, reduce your position by half to secure your principal. Continue holding until profits reach 50%, then sell half of your remaining position. The rest is pure profit, allowing it to run further. This staged selling method helps lock in gains and prevents greed from causing you to miss subsequent rallies.

**Systems Are Better Than Betting on Quick Riches**

Some think this set of rules is too rigid, but in the crypto world, it’s precisely this “rigidity” that helps cure those flashy ideas.

These principles are survival rules summarized after repeated real trading validation. Following them helps you stay steady, move further in the market. As the market changes daily, when new key levels or technical signals appear, your thinking will be updated immediately.
