Having been in the crypto world for 8 years, experiencing rollercoaster-like market conditions, I’ve come to realize one principle: true profits don’t come from luck, but from repeated lessons learned through losses.

Whenever I discuss coin selection and trading strategies with others, I always emphasize that the method I currently use is actually very simple. But it’s precisely these seemingly straightforward things that are the real secrets to making money.

Many people see the market’s ups and downs and can’t resist wanting to "rush in," only to end up making chaotic trades and causing their accounts to plummet. I’ve made that mistake too, and looking back, it was indeed very irrational.

**The logic of coin selection is very straightforward**

I always start by looking at the gain leaderboard. Why? Because only coins that are already moving have active market participation and subsequent opportunities. If a coin is completely flat, why should I buy it?

After choosing the right coins, don’t get obsessed with minute-level K-line fluctuations. I pay more attention to the monthly MACD indicator. When a golden cross forms, I enter the market; if not, I stay in cash. Short-term volatility can tell you some things, but real opportunities are hidden in long-term trends. Stories of oversold rebounds are just for listening; betting on such low-probability events is basically giving away money.

**The 70-day moving average is my lifeline**

The most closely watched indicator every day is the 60-day line. When the price stops falling near the 70-day moving average and trading volume begins to increase, that’s a signal—meaning I dare to add to my position. At this point, confidence is needed; the market will give opportunities. When the signal appears, stay steady; if not, keep waiting.

Once I enter a position, I never get greedy. If it’s bullish, I hold; if it breaks support, I cut losses immediately. Many people’s problem is "reluctance to sell," always waiting for a rebound, which eventually turns profits into losses.

Profit-taking also needs to be disciplined. Don’t expect to take all gains at once. Take half off at a 30% rise, then when it rises another 50%, take half again. The market is constantly changing; if you miss this wave, there will be another. No need to be stubborn.

**The core discipline: sell when it breaks below the 70-day line**

This is a rule I never deviate from in every trade. No matter how long you’ve held or how high your expectations are, once it breaks below the 70-day line, it’s a signal—get out immediately. Don’t fight the market, and don’t gamble with your own life. This rule is truly the key to my survival until now.

The simpler the crypto market, the more profitable it is, because simplicity makes execution easier. Those who are always thinking about "turning things around in one shot" end up being painfully taught by the market. The real money is accumulated through day-to-day discipline and managing your emotions well.

The crypto market is quite forgiving to obedient traders, but it will severely punish those who don’t understand the rules.
