#Strategy加码BTC配置 Quantum computing has been a hot topic in the media. But what is the real situation? If even factoring 21 into 3 and 7 isn't straightforward, how can it possibly crack Bitcoin?

Let's clarify—even if we use the most powerful Grover algorithm in quantum computing, dealing with SHA-256 only reduces the difficulty from 2^256 to 2^128. Sounds like an improvement? Actually, it's still an astronomical number, physically impossible to achieve.

What's more upsetting is that if you actually use a quantum computer to attack a running Bitcoin network, you'd need to perform massive calculations within a few minutes—this difficulty is tens of thousands of times more absurd than the leap from the computers of the 1950s to today. Modern cryptography has long accounted for Moore's Law and the growth of computing power.

So, those claims about quantum fears and quantum cracking of Bitcoin? It's time to wake up. The hype far exceeds the actual threat. The security of $ETH and $BTC is not a big issue in the short term.
