Having been in the crypto world for so many years, from the initial frequent liquidations to later being able to steadily accumulate wealth, I've gathered quite a bit of knowledge that I want to share.

Recently, many people have asked about the coin selection logic and trading strategies. In fact, there's no need for a complicated system. The method I use now can be summed up in a few iron rules; it's straightforward and blunt, but this set of principles allows people to quietly make money.

In the early years, I indeed fell into pitfalls and watched too many people chase high prices and sell low, only to get liquidated. Later, I summarized a few key elements.

**Coin Selection Logic**

Don't choose coins randomly. Prioritize those coins at the top of the gainers list; these coins have strong liquidity and active chips, making them worth participating in. Those coins that are in a sideways trend and lifeless are the easiest to get trapped in, and this is an iron rule.

**Trend Judgment**

Focusing on short cycles will only be confused by market noise. Use the monthly MACD to determine the trend; this is the stabilizing indicator. If a golden cross appears on the monthly chart, consider getting on board. If there's no golden cross, hold a Short Position and wait; short-term fluctuations are all just illusions. I now choose to avoid those bull traps that occur after an oversold rebound.

**Timing for Increasing Position**

The 60-day line is the lifeline for determining profitability. When the coin price retraces to the 60-day line and trading volume increases, this is a signal to increase the position. Compared to blindly buying the dip, waiting for clear signals is much more prudent.

**Exit Management**

Once you've built a position, as long as the trend hasn't broken, continue to hold. If it falls below a key support level (for example, below 3% of the entry price as a stop loss), exit immediately. Don't fantasize about a rebound; hesitating to sell can wipe out profits.

**Take Profit in Segments**

When the increase reaches 30%, reduce half of the position; when it reaches 50%, liquidate the remaining. Preserving profits is the hard truth; after all, opportunities in the crypto world come one after another, and missing one isn't the end.

**70-Day Line Rule**

This is a hard rule. Under any circumstances, as long as it effectively breaks below the 70-day line, clear all positions, regardless of whether it's a profit or a loss at the time. This rule has helped me avoid three major risks of big dumps.

**Core Idea**

Making money in the crypto world is actually this simple: the simpler the strategy, the easier it is to execute; complex operations will only confuse your mindset. Don't think about getting rich overnight; it's discipline and mindset management that allow you to accumulate bit by bit.

All of this has been summarized with real skin in the game; if you follow it, you can avoid many detours.
