#数字货币市场洞察 has been in the crypto market for eight years, and the most unforgettable lesson happened during the 2017 bull market.

Back then, I spotted $ADA and started building positions in batches at $0.03. Three months later, it soared to $1.2, with nearly 40x gains on paper. Every morning I woke up counting the extra digits in my account, already planning my down payment for a house.

The result? Greed took over, and I didn’t sell a single coin.

Later, $ADA crashed all the way down to $0.2, giving back 80% of the profits. The house plan naturally fell through. That was a hard fall, but it brought me an important realization: in this market, buying is just entry-level—selling is the real skill.

The following profit and loss control system is a survival rule I learned the hard way. It’s especially suitable for ordinary players who don’t have time to watch the market all day.

**Let’s talk about profit-taking first**

Now I use a laddered exit strategy.

Suppose a coin goes from $1 to $2. I’ll first sell 30% of my position to lock in the principal. When the price hits $3, I sell another 30%, and for the remaining 40%, I set a trailing stop order—if it pulls back 15% from the peak, it will auto-sell everything. This way I can catch the main leg of the rally without riding the roller coaster all the way back down.

**Now about stop-loss discipline**

I set a hard rule for myself: never let a single trade lose more than 5% of the principal.

For example: if I open a $10,000 position, I’ll cut my losses when the floating loss reaches $500. In practice, I like to preset conditional orders: after buying, immediately set a stop-loss trigger at -10%, like tying a safety rope to every trade. Don’t be afraid to miss out—there are always opportunities in this market, but if your principal is gone you’re truly out of the game.

**Here’s a counterintuitive tip: lower your expectations**

Many people always want to sell at the very top, but often miss the best exit window because of it. My goal is simple now—just take the middle of the fish, leaving the head and tail for others. This approach actually let me lock in a steady 35% return this year.

Honestly: over the years I’ve seen countless stories of overnight riches, but far more people burn through their principal riding the market’s ups and downs. The ones who actually take profits are those who execute their rules with machine-like discipline.

I remember once after stopping out, the coin doubled again and a friend laughed at me for being timid. But I have no regrets—because three months later, that coin went straight to zero.

Surviving in the crypto world is always more important than making quick money.
