Bitcoin has twice attempted to breach the $80,000 mark in the past week, only to face resistance and retreat to approximately $77,000, marking a 1.4% decline over the past 24 hours but a 2.6% increase for the week. Despite the setbacks, institutional interest remains robust, with U.S. spot Bitcoin ETFs seeing $1.9 billion in net inflows over the past seven days. The resistance at $80,000 is significant, with sellers consistently absorbing buying pressure at this level. This psychological and technical barrier has yet to be overcome, despite the strong institutional demand. BlackRock's iShares Bitcoin Trust, which launched in January 2024, now manages $63 billion in assets, highlighting the rapid growth of Bitcoin ETFs. Market sentiment has improved, with the Fear and Greed Index rising from 29 to 47 in a week, indicating a shift from fear to neutrality. As Bitcoin continues to test the $80,000 resistance, the market's direction heading into May will depend on whether it can finally break through this level or face further rejections.
