Bitcoin falls below $66,000, erasing most of the gains made during the week, as macro risks cause investor panic. The CoinDesk 20 Index drops 2.3%, with major altcoins and crypto stocks (such as Coinbase and MicroStrategy) also declining. This sell-off coincides with a PPI report that exceeded expectations, widening credit spreads, and escalating geopolitical tensions, leading to capital flows into safe-haven assets like gold and U.S. Treasuries.
