Bitcoin (BTC) shook off a brief push to $76,000 last week, only to reverse sharply as hotter-than-expected U.S. inflation data and a more hawkish Federal Reserve narrative tightened financial conditions and revived risk-off positioning across markets. In a weekly note published Sunday UTC, Bitfinex Alpha said BTC opened the week near $71,000 and rallied roughly 7% over two sessions to around $76,000 before momentum faltered.
