The analyst emphasized that the network requires immediate action to address this existential security threat.

Bitcoin's Short-Term Holder Net Unrealized Profit/Loss has moved into negative territory, signaling pressure on recent buyers.

Bitcoin recovered to $110,000 this week after opening at $107,000, yet faces challenges maintaining momentum near all-time highs.

Standard Chartered's head of digital asset research Geoff Kendrick said Bitcoin could temporarily fall below $100,000 due to escalating U.S.–China trade risks.

Bitcoin is testing a critical support level at $108,500, where 15% of BTC supply sits at a loss, according to Glassnode data.

Historical patterns indicate that failure to hold the $108,500 threshold could trigger a deeper correction toward $97,500, where 25% of supply would be underwater.
