Is quantum computing approaching BTC's defense line? Record-breaking breakthroughs with a 512-fold surge, risks unfolding in advance

Independent researcher Giancarlo Lelli successfully cracked the cryptographic keys used to protect Bitcoin, receiving the Q-Day Award from Project Eleven and a reward of 1 BTC.
He combined publicly available quantum hardware with a variant of Shor's algorithm, successfully cracking a 15-bit key among 32,767 possibilities, a difficulty increase of approximately 512 times compared to the previous 6-bit record.
What does this mean?
The threshold for quantum attacks is lowering, and technological progress is accelerating toward practical application.
Data shows that approximately 6.9 million BTC are in potentially vulnerable static addresses, including about 1 million BTC held by Satoshi Nakamoto.
Countermeasures:

The Bitcoin community has proposed BIP-360, introducing quantum-resistant address schemes

Ecosystems like Ethereum, Ripple, Tron, and others are also advancing quantum defense upgrades

Structurally, this is not a question of "whether it will happen," but "when it will fully arrive."
In the crypto world, the greatest risk often comes from breakthroughs at the technological frontier.
You can ignore short-term fluctuations, but you cannot ignore changes in fundamental rules. Those who truly can navigate cycles always prepare in advance for the future.
