Galaxy Research monitored that a physical Casascius Bitcoin minted between 2011 and 2013 (denomination of 25 BTC, approximately 1.78 million USD) had its private key extracted and completed an on-chain withdrawal.It is reported that Casascius Coin is an early physical collectible of Bitcoin, which contains real BTC private keys sealed inside.

This series was discontinued in 2013, and there are still tens of thousands of BTC sealed in unopened Casascius physical coins.

The co-founder of the Bitcoin custody company Casa, Jameson Lopp, stated on social media, "I have been publicly discussing the risks posed by quantum computing to Bitcoin for 18 months.My main conclusion is: I sincerely hope that the development of quantum computing can stagnate or even decline, because adapting Bitcoin for the post-quantum era will be very tricky for many reasons." Quantum computers will not break the Bitcoin network in the short term. We will continue to observe its development.However, a comprehensive overhaul of the Bitcoin network (and an unprecedented migration of funds) may take 5 to 10 years. We should hold the best hopes, but also be prepared for the worst-case scenario.

According to CoinDesk, recently, two wallets associated with Casascius physical bitcoins transferred a total of 2,000 bitcoins, worth approximately $180 million, after being dormant for over ten years. These bitcoins had not been used since 2011 and 2012, when the price of bitcoin was less than $15, and now it is close to $90,000.Casascius physical coins were created by Utah entrepreneur Mike Caldwell in 2011 and are tangible collectibles that contain embedded private keys, with denominations ranging from 1 to 1,000 BTC. Each coin comes with a tamper-evident holographic seal to protect the private key underneath. Caldwell ceased production of the pre-funded coins at the end of 2013 after being labeled an unregistered money transmitter by the Financial Crimes Enforcement Network (FinCEN).The specific purpose of this transfer is unclear; it could be for sale, internal restructuring, or a precautionary measure to preserve access. It may also be related to the degradation of physical components, similar to a report earlier this year from a user claiming to own a 100 BTC Casascius bar who had difficulty importing the key into a modern wallet after peeling off the hologram.

ChainCatcher news, according to Cryptoslate, a collector who goes by the name John Galt on the Bitcoin Talk forum recently successfully redeemed a solid gold Casascius physical Bitcoin bar purchased in 2012, extracting 100 BTC from it, currently valued at over $10 million. It is reported that the bar was purchased for only $500 at the time, yielding an investment return of approximately 2,000,000%.Casascius physical Bitcoins were issued by Mike Caldwell in 2011, embedded with real Bitcoin private keys, and ceased production in 2013 due to regulatory pressure, now becoming a rare collectible in crypto history. According to data from casasciustracker.com, over 10,000 Casascius coins have been redeemed, with more than 18,000 still unclaimed.

ChainCatcher news, regarding Grok's post stating "the Bitcoin block size is approximately 664 GB, growing by about 72 GB per year, and removing the OP_RETURN limit could increase the block size by about 20%," Casa co-founder Jameson Lopp responded on the X platform, stating: If you rely on artificial intelligence to explain the technical details of Bitcoin, your experience is certainly going to be terrible. This answer is complete nonsense; the block size data based on OP_RETURN is actually much smaller than that based on witness information records.

ChainCatcher news, Bitcoin custody company Casa co-founder Jameson Lopp posted on X reminding: Any LND (Bitcoin Lightning Network) node running a version prior to 0.17.0 should be updated immediately to fix a critical vulnerability.According to information shared by X platform user @DavidShares, LND versions prior to 0.17.0 are susceptible to malicious DoS attacks. Running an outdated version of LND puts funds at risk due to the ease of attack. The low cost and simplicity of the attack make this vulnerability very serious. This vulnerability was discovered a year ago, in June 2023.

ChainCatcher news, Jameson Lopp, co-founder of the self-hosted digital asset solution provider Casa, stated on social media that while attacks on cryptocurrency whales are still relatively rare, their numbers are greatly underestimated. Many victims are afraid to consult law enforcement due to concerns about attracting more attention.Brian Lockhart, the Director of Technical Project Management at Bitcoin miner Core Scientific, supported this statement in the comments section, emphasizing that victims do not want to "feel embarrassed" by disclosing that they are victims of cryptocurrency hacking, and it may also attract the attention of the IRS and lead to further attacks.

ChainCatcher message, regarding a Bitcoin on-chain transaction fee that reached 19.82 BTC at 1 AM today. Jameson Lopp, co-founder and CTO of the self-custody wallet Casa, stated on the X platform: "This appears to be a transaction from an exchange or payment company with a software vulnerability, which received over 60,000 transactions and sent over 60,000 transactions from the same address (bad practice), and likely miscalculated the change output. The address where the fee calculation error occurred has the characteristics of a corporate hot wallet used only for withdrawals. It seems to only occasionally receive deposits from one address to replenish the balance."Previously, on-chain data showed that at 1:10:01 AM Beijing time today, a Bitcoin on-chain transaction occurred with a fee as high as 19.82 BTC (worth nearly $510,000), setting a historical record.
