VanEck: Mining Activity Decline Is a 'Bullish Signal' for Bitcoin Price
**Dec. 23**
VanEck’s latest report notes a recent drop in Bitcoin mining activity could signal an impending price rise—aligning with historical market trends.
In their Monday report *Mid-December 2025 ChainCheck*, VanEck analysts highlight Bitcoin has historically seen higher odds of positive returns following falling mining activity. Since 2014, Bitcoin’s forward 90-day return has been positive 65% of the time when the network’s hash rate dropped, versus 54% when hash rate rose.
The analysts add: “Empirical evidence suggests hash rate drops may benefit long-term Bitcoin holders,” calling the pattern a “reverse signal” tied to miner capitulation—where weaker operators exit the network amid financial strain. This correlation is repeating now: Bitcoin’s hash rate fell 4% in the month ending Dec. 15, marking its biggest drop since April 2024.
The report further notes: “Additionally, when hash rate compression lasts for an extended period, positive expected returns tend to be mo

macOS Trojan Update: Spreading through Signed App with User Data Encryption Poses Increased Stealth Risk
On December 23, SlowMist Chief Security Officer 23pds shared a post noting that the **MacSync Stealer** malware—active on macOS—has undergone significant evolution, with user assets already compromised.
Early versions relied on "drag-and-drop to terminal" and "ClickFix" tactics to trick users; the latest iteration has upgraded to **code-signed, Apple-notarized Swift applications**, drastically boosting stealth.
Researchers identified the sample spreading via a disk image (DMG) named `zk-call-messenger-installer-3.9.2-lts.dmg`, disguised as an instant messaging or utility app to lure downloads. Unlike prior variants, the new version requires no terminal actions from users—instead, a built-in Swift helper fetches and runs code from a remote server to execute information theft.
The malware is fully code-signed and notarized by Apple, with developer Team ID `GNJLS3UYZ4`. At the time of analysis, Apple had not revoked its associated hashes, granting it higher "trustworthiness" unde

Analysis: Bitcoin on Track for Worst Q4 Performance Since 2018, Market Rebound 'Lackluster'
December 23rd – Bitcoin recently rebounded to nearly $90,000, giving the crypto market a short-term lift. However, analysts broadly agree this move does not signal a trend reversal.
Per CoinGlass data, Bitcoin has dropped more than 22% in the fourth quarter (Q4) this year—potentially marking one of its worst-performing Q4s since 2018, trailing only major bear market years.
While the total cryptocurrency market cap has reclaimed the key $3 trillion threshold, market sentiment remains cautious. Analysts note this rebound stems more from a technical bounce after a prolonged decline than fresh capital inflows. Alex Kuptsikevich, Chief Market Analyst at FxPro, stated the current trend is “not a true recovery,” with only limited improvement in market sentiment.
As of the Asian trading session, Bitcoin is hovering around $88,000—still roughly 30% below its 2025 high and under its year-opening level. Major tokens are overall volatile: XRP, ETH, SOL, ADA, and DOGE posted slight gains,
