Bitcoin's recent rally toward $87,000 stalled after whales sold over 30,000 BTC and the price hit the upper boundary of a two-week trading channel. The $87,000 level has acted as consistent resistance, capping upside momentum despite earlier bullish sentiment. Analyst Ali Charts identifies $82,500 as the next critical support zone near the channel's lower boundary. A pullback to this level accompanied by renewed whale accumulation could signal a buying opportunity, with expectations for a subsequent retest of the $87,000 resistance area.
