I just consulted with a contract expert, who turned a 10,000 principal into an eight-digit fortune. This experience is more thrilling than a novel! After some soft and hard persuasion, I got nine key insights to share with all contract players:

If your principal is under 100,000, catching one big market wave each day is enough; don’t get too carried away! Those who go all-in every day will find themselves in a grave situation.

When encountering significant good news, remember to sell on the following day if it opens high! Good news turning into bad news is a well-tested strategy in the crypto world.

You must reduce your positions before holidays and major events! Historical experience shows that whenever the Federal Reserve raises interest rates or on delivery days, the market goes wild. If you don’t understand, stay out until the direction is clear.

For mid to long-term operations, be like a sniper, laying low with light positions! Don’t use up all your bullets; leave enough room for averaging down. Heavy positions in mid to long-term trading? You'll learn your lesson in no time.

Short-term trading is all about "fast, precise, and ruthless"! When you see the right direction, go all in; making 10%-20% profit means you must exit. When the market is sluggish, it’s better to stay out and watch than to get itchy fingers.

Remember this mantra: slow rises correspond to slow falls, and explosive rises must lead to explosive falls! If you see the market suddenly go wild, quickly set your stop-loss.

What to do if you're on the wrong side of the direction? Three words: cut losses! Immediately! Stop-loss is a way of making money in disguise; as long as you have the mountains intact, you’re not afraid of a lack of firewood.

Short-term traders should have the 15-minute K-line chart glued to their screens! Use the KDJ indicator, clearly seeing golden and dead crosses, making entry points precise.

Techniques are superficial; mentality is the key! If your main coin halves, don’t smash the keyboard; if it skyrockets tenfold, don’t shout bull market; securing profits is the real skill.

To put it simply, the crypto world is a life-and-death situation between retail investors and whales; without insider information, you’re destined to be the fish on the chopping board!

Finally, here’s a piece of advice for everyone: every penny you earn dances within your cognitive range. Big ups and downs are the norm; stay steady and don’t get reckless; we’ll meet at the summit!
