[Analyst: If Bitcoin Retraces to $82,500 and Whales Accumulate, It May Confirm a Buying Opportunity] According to monitoring by Ali Charts, Bitcoin's recent attempt to break through $87,000 was met with resistance. During this process, whales sold over 30,000 BTC, and $87,000 happens to be the upper boundary of the channel where Bitcoin has faced consistent resistance over the past two weeks. Currently, Bitcoin has pulled back again, with the short-term downside target pointing to the lower boundary of the channel, around $82,500. If Bitcoin drops to $82,500 and whales begin to accumulate again, it may confirm a buying opportunity, with the target being another rebound to $87,000.
