Bitcoin retakes $77K as Iran risks darken outlook

Bitcoin (BTC) rose to $77,180 on Friday after President Trump highlighted the reopening of the Strait of Hormuz, lifting the Crypto Fear & Greed Index to 61—its first "greed" reading in months. Sentiment turned less certain on Saturday after Iran said it would reimpose restrictions on the strait, and IRGC gunboats opened fire on a tanker transiting the waterway. Despite the geopolitical headlines, spot Bitcoin ETFs have attracted $1.6B in inflows in April, with BlackRock's IBIT bringing its cumulative total to $64.35B. BTC futures open interest climbed to $61B this week, the highest level in months.
