#量子计算威胁 Seeing the resurgence of the quantum computing threat discussion, it's time for a serious analysis. The potential risk of 1.7 million BTC is indeed eye-catching, but the key is to understand clearly — this is not something that will happen tomorrow.

Nic Carter is right; going from theoretical breakthroughs to practically cracking Bitcoin is still a decade-long engineering challenge. But this precisely highlights the tricky part: it's not that the technology is impossible, but that the time window and coordination costs are prohibitively high. Soft fork upgrades, migrating tens of millions of addresses, handling abandoned BTC addresses — each is a political and technical double bind.

From a follow-trade perspective, this kind of systemic risk is actually an invisible signal of risk concentration. In the short term (3-5 years), the quantum threat has limited impact on trading strategies, but long-term holdings need to adjust their approach. My suggestions are:

For **risk-tolerant** traders, you can maintain high leverage follow strategies; quantum risk is not the main concern yet. For **conservative** traders, now is the time to consider regularly locking in profits and gradually taking profits — not out of pessimism, but to leave yourself a window of time to respond in advance.

Finally, this serves as a warning that we should pay attention to those traders who can foresee systemic risks and proactively hedge. True experts never just look at short-term profit curves; before placing bets, they think about the worst-case scenarios. That’s the logic worth following.
