Analyze BTC BTC remains above key short-term support, and the rebound structure has not yet broken below $75.000, which is an important observation level for the current rebound structure. BTC still retains room for upward testing of higher resistance levels in the short term. From the 4-hour chart, it can be seen that BTC is still in the higher range of the upward structure after rebounding from its April low. Although BTC has fallen from recent local highs, it has not yet fallen below the main support level. $75.000 is a key observation level for whether the current bullish structure continues. As long as the price remains above this level, the existing rebound path has not been negated. If there is a subsequent upward breakthrough, the first major resistance level will be around $81.960. However, BTC has not yet completed an effective breakthrough. The price is still running below the near end resistance, and the short term is more like a consolidation stage before further direction selection. If it falls below $75.000, the current structure will significantly weaken, and the market may shift its focus to lower support ranges. Overall, BTC is still standing above short-term support, and the rebound structure has not been disrupted. However, before the resistance above is broken, the market is still in the stage of consolidation and confirmation.
