I am 45 years old this year, and I have been involved in cryptocurrency investment for exactly ten years. My current lifestyle is: I check the market daily, execute a few contracts, and strategically allocate some spot investments; I do not need to consider a budget for daily expenses, I have hardly encountered any business disputes, and my worries are few.

Looking back on these ten years, the experience I most want to share is: in the crypto world, mindset is always more important than technology. Here are the practical insights I have summarized over the years:

1. Bitcoin is the "barometer": Most of the time, the entire market observes its trend. However, there are exceptions—mainstream coins with solid fundamentals, like Ethereum, can occasionally exhibit independent market movements; but the vast majority of altcoins still fluctuate along with Bitcoin, making the market effect very obvious.

2. There is a "seesaw effect" between Bitcoin and USDT: When USDT continuously appreciates, it often signals that Bitcoin may drop; conversely, when Bitcoin surges significantly, it may be a good time to convert back to USDT and lock in profits.

3. Watch for "spike events" between 0-1 AM: Domestic investors can take advantage of this pattern—before sleeping, place a low buy order for a coin you are optimistic about, while also setting a relatively high sell order for your existing holdings. The market often experiences sudden and drastic fluctuations during this time, making it easy to trigger these orders, essentially allowing you to "earn while you sleep."

4. Pay special attention to the market at 5 PM: This is a "key time point" familiar to veteran players. As the European and American markets begin to become active, the market tends to experience significant fluctuations. I have personally witnessed many major upswings and downswings concentrated during this period, so I recommend paying more attention to the market at this time.

5. View "Black Friday" rationally: There is a saying in the market that "Fridays tend to drop significantly," and while it has indeed happened a few times, significant gains or sideways movements on Fridays are also quite common, and the accuracy is not stable. There is no need to be overly anxious; just pay appropriate attention to the news.

6. If a coin with trading volume drops, don't rush; patiently wait for a rebound: If you hold a project that has real trading volume backing it and is not a pump-and-dump coin, even being stuck in a position short-term should not cause anxiety. With patience, you can generally break even—within as little as three to four days, or a month at most. If funds allow, you can buy in batches to lower your average cost, which can help you break even faster; if funds are insufficient, just be patient, and it is likely to recover.
