Back in 2017 when I first entered the crypto space, I was as naive as all newcomers—staring at the K-line and thinking "a big turnaround" was just around the corner. And what happened? Repeatedly taking losses, getting liquidated, and almost being淘汰ed by the market. Eight years have passed in the blink of an eye, and my account has gone from constant losses to stable profits, only then realizing this truth: the market does not mistreat those who listen, but it will definitely teach a harsh lesson to those who gamble foolishly.

Today I want to talk about not some profound theory, but four simple rules I’ve learned through real money.

**Rule 1: Only look for opportunities in coins that have "moved"**

In my early days, I especially liked to buy the bottom of coins that no one paid attention to, thinking that cheap equals opportunity. The result? I ended up digging my own pit. Now, my approach is to first scan the top gainers daily, then check the monthly MACD. I never move before a golden cross occurs. I still remember the rebound of SOL in 2023, which only started after the monthly golden cross. Those dead coins? No matter how cheap, don’t touch them—if no big funds are paying attention, entering is just a waste of time and effort.

The market always favors the strong. Instead of digging through trash, it’s better to follow smart money and drink some soup.

**Rule 2: The 70-day moving average is a life-and-death line; break it and sell immediately**

Once held a coin for half a year, saw the profit double, but didn’t take profit in time, and a wave of correction wiped it all out. Now, the iron law is simple: if the price is above the 70-day moving average, hold with confidence; if it breaks below, sell immediately.

Before the Luna crash in 2022, it repeatedly fell below this line. Many still hoped for a rebound to save the situation, but in the end, they lost everything. The moving average is the clearest signal language of the market—don’t fight the trend, and don’t gamble with your life.

**Rule 3: Take profits in stages, don’t try to eat the whole pie at once**

Take 30% profit when it rises by 30%, then take half when it rises by 50%. This way, you can lock in gains and avoid greed causing repeated losses. I’ve seen too many people only focus on the sky, only to end up on a roller coaster back to the starting point.

**Rule 4: Mindset is more important than technicals**

This is the hardest but most crucial rule. Being able to accept small losses, set stop profits regularly, and stay disciplined in front of temptation—doing these is more valuable than studying complex indicators.

The crypto world is a true test of character. Those who stick to the rules end up making money, and not a single smart gambler has escaped unscathed.
