On December 15th, a heated debate erupted on social media over whether quantum computers could potentially hack Satoshi Nakamoto’s Bitcoin wallet and dump its holdings—sparking reactions after YouTuber Josh Otten shared a BTC price chart showing the token plummeting to $3. Otten argued that if a powerful enough quantum computer stole the roughly 1 million BTC held by Bitcoin’s anonymous founder and dumped it on the market, such a $3 crash could occur. Longtime Bitcoin hodler Willy Woo pushed back, noting: “Many OGs (original gangsters, early holders) would buy the dip in a flash crash like this. The Bitcoin network would survive, and most BTC wouldn’t face immediate risk.” He further explained that around 4 million BTC—including Satoshi’s holdings—sit in P2PK (Pay-to-Public-Key) addresses. These addresses expose the full public key when spent on-chain, making them theoretically more vulnerable to quantum attacks. Woo added that once a wallet’s full public key is revealed on

December 15th, cybersecurity nonprofit Security Alliance warned it has been detecting dozens of scam attempts daily from North Korean hackers, with the attacks targeting victims via fake Zoom calls. The scam—tricking victims into downloading malware during fake Zoom calls to steal sensitive data including passwords and private keys—has stolen more than $300 million worth of assets from victims, per security researcher Taylor Monahan. Here’s how the scam typically unfolds: It starts with a Telegram message from an account often linked to someone the victim “knows.” That familiar connection lowers the victim’s guard. The chat then shifts to an invite to “catch up via Zoom.” Once the call begins, the hacker claims audio issues and sends a supposed “patch file.” Opening the file infects the victim’s device with malware. The hacker then wraps up the fake call with an excuse like “let’s catch up another day.”

On December 15, Coinglass data indicates that: - If Ethereum (ETH) breaks above $3,200, total short liquidations across major centralized exchanges (CEXs) will hit $825 million. - Conversely, if ETH falls below $3,000, total long liquidations on these major CEXs will reach $865 million. BlockBeats Note: Liquidation charts do not display the exact number or value of contracts scheduled for liquidation. Instead, the bars on these charts reflect the relative importance of each liquidation cluster versus its neighboring clusters—i.e., "liquidation strength." In short, liquidation charts show how heavily a target price level will be impacted when reached. A taller "liquidation bar" signals a stronger price reaction due to a liquidity cascade at that level.
