A friend who recently entered the market asked me whether dollar-cost averaging into BTC is reliable. I didn't talk about beliefs or faith; I just discussed it purely from the perspective of accounting logic.

To put it simply, work income is shrinking every day—inflation is ongoing. But BTC has a total supply of only 21 million coins, which is a hard cap; once mined out, that's it. Over more than a decade of market practice, the long-term gains have indeed far exceeded traditional assets. This isn't some speculative logic; it's based on the most fundamental supply and demand relationship.

The beauty of dollar-cost averaging is that you don't need to watch the market every day guessing the highs and lows. Gradually converting your continuously devaluing fiat currency into scarce assets is called asset allocation, not gambling. It reduces emotional stress and offers probabilistic advantages in returns, making it quite suitable for working professionals.

But you need to be clear about your position size—the key depends on your principal amount.

If you only have a few tens of thousands, heavy concentration in a single coin is too risky; even doubling your investment won't significantly change your life. In this case, it's better to lower your dollar-cost averaging amount and use the freed-up funds to explore other promising but riskier assets. This is a reasonable risk-reward balance.

If you have hundreds of thousands of idle funds, your allocation strategy is completely different. Allocate 50% steadily into BTC or ETH as your cornerstone assets, and the remaining 50% to other opportunities. Historical patterns also confirm that the bull market usually starts with major coins moving first, followed by second-tier coins, and finally a frenzy of small coins. Grasping this rhythm can lead to significant differences in returns.

The easiest trap for beginners is not being able to hold. Watching others' coins hit daily limits while your own stay stagnant, you can't help but frequently cut losses, switch positions, chase highs, and sell lows, ultimately becoming a bystander in this round of the market.

So the core principles are these: either don't play, or have a clear allocation plan if you do; either don't allocate, or prioritize your investments; or don't participate at all, but be mentally prepared to withstand volatility. Not greedy, not following the crowd, and not operating frequently are the only ways to truly benefit from a bull market.
