In crypto trading, the true difference between winners and losers often isn't about whether you can accurately predict the market, but whether you can control yourself.

We've seen too many traders with decent analytical skills who still end up losing everything. The reason is simple—being driven by emotions. When a volatile market presents tempting entry points, they can't resist jumping in; when they've already made a profit and see the market still rising, they greedily add more. What's the final result? Profits are quickly wiped out, or even turned into losses.

In full-position trading, there are two ironclad rules that can save your life.

**Rule 1: Do Not Enter During Sideways Markets**

Crypto markets generally fall into two categories—trending and sideways. Sideways markets are characterized by prices bouncing within a range, fluctuating up and down without a clear direction. Many people can't sit still watching such markets, thinking that entering at this price level guarantees profit, but the result is often catching a falling knife.

Why? Because no direction means no certainty of profit. You might get lucky and make a quick short-term gain, but over the long run, such operations will lead to more losses than wins. Instead of blindly guessing in this fog, it's better to honestly observe and wait until a clear trend emerges before taking action. That’s being responsible for yourself.

**Rule 2: Do Not Add to Profits**

This rule tests human nature the most. After opening a position and making a profit, you'll see the market still moving favorably. Many then think, since the market is so good, why not add some more to earn even more?

The problem is—by this time, the market is often already in the middle or late stage, and adding positions can easily turn into a trap. Once the trend reverses, the profits you've gained can be wiped out instantly, and in severe cases, turn into losses. Instead of gambling like this, it's better to hold onto the profits you've already made and wait for the next opportunity.

**The Core: Certainty**

Trading, in essence, is about seeking certainty. Only engage in markets you understand, hold onto the profits you deserve, and don't break your rules out of FOMO or greed. Opportunities with BTC, ETH, and other mainstream coins are plentiful—you don't need to chase every single one.

Disciplined traders may not make the fastest money, but they last the longest.
