Getting into a contract and losing money is not scary; what's scary is constantly repeating the same mistakes. Many people fall into a loss cycle, essentially because they haven't understood a few fundamental trading principles.

Let's start with the two most basic things—taking profit and stop-loss. It sounds simple, but very few actually do it. Taking profit can curb that bottomless greed; don't always get caught up in the false dilemma of "selling early." The crypto market's money is indeed endless, but your principal can be wiped out all at once. Stop-loss is even more brutal; it’s the courage to face mistakes head-on. Most people are gambling on "holding on until it reverses," but end up getting liquidated. Instead of hoping for miracles, it’s better to cut losses and stop bleeding in time.

Then there's the trap of trading frequency. Thinking about going long and short every day often results in getting cut on both sides. When entering a high-leverage contract, the trading fees already eat up 1-2% of your gains, plus reckless trades without logic, basically giving money to the market. Mastering one direction is already a good start.

When the market is unclear, staying out of the market is actually the smartest choice. Many fear missing out, but think about it—missing out at most means missing a wave of profit, while reckless trading can wipe out your entire principal. No matter how you calculate it, that’s not worth it. Trading relies on probabilistic advantage, not on always predicting correctly.

Building a winning rate takes time; don’t expect to turn things around with a single heavy position. Small capital, low leverage, and continuous refinement of your trading system—even earning just a few points daily—will, over the long term, far surpass those who blow up their accounts relying on luck.

The most fatal mistake is going all-in with a big position. No matter how clear the trend, sudden news can overturn everything in a second. Without a stop-loss, heavy positions are like setting a timed bomb for yourself. Opportunities in the crypto space are never lacking; there will be plenty of market moves in the coming years. Why risk everything on a single trade?

The last point, which is the most difficult but also the most core—unity of knowledge and action. There are many who understand the principles, but very few can actually execute. To go from a rookie to a survivor requires discipline, decisiveness, and even more so, that ruthless attitude. Without these qualities, no matter how much technical analysis you do, it’s just self-deception.
