Quantum threat to Bitcoin? 14 years later, 80,000 BTC just moved


80,000 BTC Mobile: What does this mean?

On July 4, 2025, eight Satoshi-era Bitcoin wallets moved a total of 80,000 BTC. With 10,000 BTC per wallet, there is inevitably turmoil in the cryptocurrency space.

It is generally believed that the Satoshi era spans from 2009 to 2011. During that time, Bitcoin (BTC) can be traded or mined through conventional computer processors. Eight dormant bitcoin wallets Each person recently sent about 10,000 BTC transactions. This leads to speculation The threat of quantum computing Causes transfer.

Arkham Reports BTC Whale Movement

Coins are not sent directly to cryptocurrency exchanges. They went to the new Segwit addressit is recommended to perform a security upgrade. Segwit address is considered to have greater security against quantum threats than older threats. Older addresses use paid public keys (P2PK) or reused P2PK hash (P2PKH), which is more fragile.

Some posts on X suggest that the transfer may show security vulnerabilities or quantum concerns. However, these claims lack evidence and seem to be speculative.

Between July 14 and July 15, 2025, the wallet owner sent a total of 28,600 BTC to Galaxy Digital, now worth over $3 billion. 9,000 BTCs have been sold so far, possibly triggering a downtrend on July 15, when BTC fell about 5% from its most recent all-time high of $123,000.

did you know? When the whale bought Bitcoin, the price of Bitcoin fluctuated between $0.78 and $3.37 in 2011. 80,000 BTC averages $2.45 per Bitcoin, bringing the initial investment of whales to $197,200. The price of the whale’s BTC today is about $118,000, worth $9.44 billion, an increase of about 4,800,000%.

What is the quantum threat to Bitcoin?

Quantum technology is a threat to Bitcoin because it can damage the private key of the wallet. This could risk all the bitcoins you have in that wallet.

Many believe that quantum computers may disrupt Bitcoin networks and pose serious risks to their survival. Bitcoin developers are upgrading the system to deal with future risks, although the real threat remains for years. They focus on dormant Bitcoin wallets because they are at risk of quantum attacks.

Quantum can exploit weaknesses in asymmetric encryption that protects Bitcoin wallets. This includes Elliptic Curve Digital Signature Algorithm (ECDSA) This Bitcoin is used for security.

Bitcoin wallets are secured by ECDSA to generate a pair Private key. If the ECDSA algorithm is compromised, your Bitcoin is at risk. Experts believe that practical quantum attacks may occur within five to 20 years and regard 2030-2048 as a possible date.

Old wallets are most vulnerable to quantum attacks because they use P2PK or reused P2PKH Addresswhere public keys are exposed. It is estimated that 5.9 million BTC (about 25% of the supply) are in P2PK or reused P2PKH addresses; therefore, these coins are vulnerable to future quantum attacks.

80,000 BTC transferred to P2PK address. Their public keys have not been exposed yet because these are old bitcoin transactions. This means they were quantum-safe at the time. Moving them to a Segwit address further enhances security.

Bitcoin developers led by CASA founder and CTO Jameson Lopp proposed a Bitcoin Improvement Recommendations (BIP) Solve the potential threat of quantum computing to Bitcoin security. The proposal aims to protect the network by freezing and eliminating wallets vulnerable to quantum attacks, which could hurt 25% of the Bitcoin supply, including an estimated 1 million BTC held by Nakamoto.

Bitcoin whales are not active for 14 years

Arkham Bitcoin Whale analyzed eight wallets and found that they belonged to the same entity. This has sparked speculation about the recent Bitcoin whale.

A crypto whale is an individual or entity with a large number of specific cryptocurrencies that are usually sufficient to influence market prices. one Bitcoin Whale After 14 years of inactivity, suddenly, he suddenly moved out 80,000 BTC. The Bitcoin Whale Tracker analyzes blockchain data and transactions, but as an open ledger, everyone can see the blockchain.

Suspicious activity was recorded the day before the BTC transfer. Transaction of 10,000 Bitcoin Cash (BCH) Made from the relevant wallet cluster, probably testing private key access. This has caused speculation about potential hackers, such as Common cases Director Conor Grogan, although no evidence has been found.

However, one of the most supported theories is that this is Roger Ver’s Bitcoin movement, as he has been involved in Bitcoin early on since 2011.

He was released on bail in June 2025 before the campaign took place, sparking further speculation that the wallet was his push.

did you know? These 10,000-BTC moves come from eight wallets. Each marks the largest Bitcoin transaction ever. The previous record for the largest single-person transaction in Bitcoin history was only 3,700 BTC.

What is an op_return message?

The OP_Return message is a feature of the Bitcoin blockchain, which allows users to embed a small amount of data into data with a maximum size of 80 bytes, directly embedding it directly into transactions, which marks the output as unpaid.

Defend Bitcoin’s 80-byte OP_Return limit

From July 1 to July 4, 2025, four Run Return Message Added to the Bitcoin blockchain. These messages are sent to several wallets at the same time.

The first one is July 1, 2025, at 00:30, read:

“Legal Notice: We own this wallet and its contents.” (Transaction ID: 4F7C80C05FD77A9C9B180F7F6400560D1AB6CF3A4BA1B6BF7429EEEEEFA500A05).

In the next few days, three more messages were sent, which finally reached the final on July 4, 2025. They need to use the private key to conduct an OnChain transaction to prove ownership by September 30, 2025.

There is no evidence of hacking. This is likely a planned spam campaign. This could be to trick the wallet owner into transferring funds to show controls. Scammers usually target dormant wallets, claiming they were abandoned.

The spam campaign has sparked speculation on various online platforms. Some Speculation The message from OP_RETTURN is a “legal stunt” or scam to put pressure on whale owners.

Others Called News “Blockchain Graffiti”. This is usually a way to fill in bold data on a chain. However, their specific focus and timing show clear intentions.
