Bitcoin experienced a 3.5% drop on Sunday, reaching a low of just above $86,000, amid escalating geopolitical tensions that have driven investors towards safe-haven assets like gold. The cryptocurrency rebounded slightly to $87,733 in early Monday trading in Singapore. Ethereum also faced a decline, dropping 5.7% before recovering 2% to close at $2,872. U.S. spot Bitcoin ETFs saw a significant net outflow of $1.7 billion over five consecutive days last week, nearly wiping out previous inflows. FalconX's Sean McNulty described Monday's recovery as a "brief respite" rather than a strong rebound, noting the absence of significant capital inflows.
