2025 has indeed tested our psychological resilience. The 41% plunge in the crypto market in the first half of the year caused many to give up, but I saw an opportunity instead.

Why do I say that? Simply put, I developed a very straightforward trading plan at the beginning of the year —坚持定投比特币 (stick to dollar-cost averaging Bitcoin). At a fixed time each month, the account automatically makes a purchase, rain or shine. Honestly, during those months of market crashes, I was nervous, but I never stopped my DCA. The obvious benefit of this approach is that the average holding price keeps decreasing, effectively lowering the cost basis at a cheaper price.

But just DCA isn't enough; I also incorporate the 200-day moving average to assess the market trend. This line acts like a "lifeline" for the long-term trend — when the price falls below it, it indicates weakness; conversely, breaking above and stabilizing above it signals the start of a genuine rebound. Following this logic, I gradually add to my position in the bottom area, rather than blindly going all-in.

Compared to that, friends chasing altcoins suffered more during the decline because altcoins tend to be more volatile, with sharper drops. I focused on Bitcoin, the main line, avoiding these traps.

By the second half of the year, the market started stabilizing and rebounding. My DCA account gradually surfaced, and now it has yielded quite a substantial return. Looking back, this "long-term DCA + technical indicator assistance" strategy validated the simplest principle in investing: time is your friend, and making decisions based on science is much more reliable than emotional reactions.
