Recently, Google and the quantum computing community dropped a 'depth charge', claiming that the speed of cracking Bitcoin is 20 times faster than expected. Many people are worried that their coins will go to zero, but don't panic. Spend three minutes reading this summary in plain language, and you'll understand everything. 👇

1️⃣ What exactly happened?
In simple terms, Google and a company called Oratomic found a new method for 'brute-force cracking'.
Previously, experts believed that cracking Bitcoin would require a 'super quantum computer' with tens of millions of parts, and it might not be built until after 2035.
But now it’s found that as long as the algorithm is optimized, the parts requirement has dropped to around tens of thousands to five hundred thousand. This means the threat could arrive between 2029 and 2032.

2️⃣ Is this a 'fatal blow' to Bitcoin?
It is a threat, but not a 'death sentence'.
Quantum attacks are like a super thief; they can target wallets with 'keyholes exposed'.

Who is most at risk? Old wallets that haven’t moved in ten years, Satoshi Nakamoto's wallet, or the receiving addresses you have been reusing.

Who is safe? As long as you use the currently mainstream hash addresses and do not reuse them, quantum computers cannot find the 'keyhole' before the transaction.
So, it feels more like a 'precise harvest' targeting specific goals rather than an instantaneous destruction of the entire network.

3️⃣ Does Bitcoin have a way to fight back?
Of course, developers have already started 'changing the locks'.
The Bitcoin community is discussing a proposal called BIP 360. Simply put, it is to give Bitcoin a 'post-quantum anti-theft lock'.

Current situation: Ethereum is moving quickly and has already set a roadmap for upgrades in 2029; the Bitcoin community is still arguing about 'how to upgrade with the least hassle', but the technical path is already very clear.

The difficulty: Bitcoin has no 'CEO', and upgrades require the approval of miners and users worldwide, which could take 5 to 10 years.

4️⃣ Will coin prices go to zero because of this?
When the news first broke, the market was indeed shocked (it dropped nearly 50%). But in the long run, big players (like Michael Saylor) hold an optimistic attitude:
If Bitcoin successfully upgrades, those old coins that lost their private keys and cannot upgrade (including Satoshi's 1 million coins) could be permanently locked or destroyed.
The result is: the circulating coins in the market will actually decrease, and the remaining coins may become more expensive due to being scarcer and more secure.

💡 Summary:
It feels more like a race between 'locksmiths' and 'lock makers'. Although the thieves' tools have upgraded, as long as we change the locks before they act, Bitcoin will still be digital gold.

✅ Advice for holders:
Do not reuse the same receiving address! Use a new address for each transaction; this is currently the simplest and most effective way to defend against quantum attacks.
