Analysis: BTC finds it difficult to stay above $80000 in the short term, leading to increased concerns about market correction According to TechFlow, on May 21st, according to The Block, Bitcoin fell below $78000 on Thursday, and market concerns about future rebound momentum continue to heat up. Data shows that Bitcoin spot ETFs have experienced net outflows of funds for four consecutive trading days, and the long liquidation of approximately $584 million at the beginning of this week continues to suppress market risk appetite. Analysis suggests that BTC will still struggle to effectively stabilize above $80000 in the short term until demand for on chain spot goods recovers. Glassnode analysis points out that Bitcoin spot CVD (cumulative trading volume difference) has been negative for nine consecutive trading days, creating the longest net selling cycle of 2026. Bitcoin briefly recovered from the key level of "real market average" of $78300 when it rebounded to $82000, but has now fallen below it again. According to historical cycles, BTC typically needs to consolidate in the region for several weeks to months in order to confirm a bull bear structural switch.
