On Wednesday, Bitcoin fell below the $92,500 mark, dropping over 3% within an hour. On the surface, the decline appears to be driven by geopolitical risks and economic data pressures, but underlying currents are surging—a calculation involving cybersecurity and future survival is unfolding.

While investors are still processing various macro news, two alarms suddenly sounded within the Bitcoin community, sending chills down the spine.

One is a nearby technical vulnerability that could directly drain your wallet. The other is the looming "quantum countdown," with experts claiming it could slash Bitcoin's value to below $50,000 within a few years.

**The Black Hole of Wallet Migration**

In early January, the Bitcoin core development team issued a warning—versions 30.0 and 30.1 contain critical flaws.

What exactly is it? If you transfer your wallet files in the old format (BDB) to the new version, in extreme cases, the software might, in a moment of brain fog, delete all wallet files on the same node at once. No backup? Then your coins are gone forever, with no way to recover.

A fix is already in progress—version 30.2 will address this issue. But until then, it is strongly recommended that everyone avoid migrating old wallets using these two versions. This is not a minor problem.

The technical vulnerability itself does not affect Bitcoin's consensus mechanism or transaction confirmation, but it has dealt a blow to market psychology. Especially for those operating nodes and long-term holders, they now need to be more cautious.
