At 25, I stepped into the world of cryptocurrency, and by 35, my account balance first hit eight figures—those few seconds staring at the screen, I thought the system was bugged.

Now on a business trip, I can book a five-star hotel for just $2,100 a night. A few crypto-themed stickers are on my suitcase, and in the airport lounge, I occasionally meet fellow travelers. A glance is enough to understand—this kind of tacit understanding is quite fascinating.

Compared to my elders in traditional businesses, my path is definitely less stressful. No inventory backlog, no daily logistics monitoring, and no dealing with clients who owe money for half a year. Of course, the price is having to get used to account figures like a roller coaster.

Many people ask me how I play. Honestly, mindset is much more important than technology. Over the years, I’ve discovered some unwritten rules:

BTC is the emotional switch of the entire market. When it rises, altcoins generally follow; when it falls, most small coins are basically sacrificed. ETH occasionally moves independently, but if altcoins want to defy the market trend? It’s pretty much impossible.

BTC and USDT are like a seesaw—if USDT premium is high, be cautious; if BTC is rising too fast, remember to take profit.

Extreme market movements often happen between 0-1 AM. Placing orders before sleep might let you scoop some bargains; the trend between 6-8 AM usually sets the tone for the whole day, worth paying extra attention.

If the market falls in the first half of the night and continues to fall later, adding to positions at this time has a high chance of rebound that day. Conversely, if prices rise in the first half of the night and keep rising later, it’s time to sell—don’t be greedy.

Around 5 PM, when US funds enter, volatility tends to amplify, concentrating both opportunities and risks during this period.

Don’t panic on "Black Friday." Check the news before deciding; don’t blindly operate based on K-line charts.

As long as it’s not a pump-and-dump project, don’t rush to cut losses when a coin with real trading volume drops. In three to five days, or at most a month, it’s highly likely to bounce back. If you have spare cash, buy in batches; if not, hold on. Patience often works better than technical skills.

The most satisfying trade I made was buying Dogecoin at 0.085 and holding until it multiplied over 20 times. In the end, you realize that trading crypto is really about whether you can sit through the ups and downs.
