Bitcoin and altcoins have risen significantly in recent days, but Bitcoin encountered selling pressure after moving above $87,000. Bitfinex analysts identify $84,000 as a short-term BTC support level and $87,722, the 2026 annual opening price, as a major resistance point. The recent correction reduced excessive market leverage, cutting open positions by more than 10% and producing about $581 million in liquidations. Bitfinex says a sustained advance now requires renewed spot-market buying, with flows into U.S. spot Bitcoin ETFs a key gauge. Daily ETF inflows fell from $999 million at the beginning of the week to $134.5 million on Friday. Strategy also bought 1,665 Bitcoin for about $142.7 million between September 21 and 27. A sustained break above $87,722, combined with stronger ETF inflows and continued institutional buying, could put Bitcoin's average Market Cap/Realized Value (MVRV) price of $96,700 in view. Bitfinex identifies $85,000-$86,500 as a high-cost resistance zone and $84,000 as critical long-term investor support. Below $81,300, the previous range peak, and with negative ETF flows, Bitcoin could test the True Market Mean level of $77,000, which analysts describe as the main support. The next major macroeconomic test is U.S. core PCE inflation data due September 30. The material is not investment advice.
