Bitcoin has fallen about 3.6%, sliding below $86,000 and edging toward the $81,000 True Market Mean support level, while liquidations near $400 million and spot bids cluster between $85,000 and $80,000. On‑chain metrics show wholecoiner inflows to Binance have dropped to roughly 6,500 BTC on a yearly average, last seen in 2018, as analysts track whether a sweep of the $80,000 area precedes a rebound toward $90,000–$100,000 or a deeper correction toward $76,000.

On December 15, Bitcoin extended its recent pullback while shares of Strategy (MSTR) dropped 7.29% to $163.55 on heavy trading volume. During the second and third quarters of 2025, the New York State Common Retirement Fund, which oversees about $284 billion in assets, increased its MSTR position to roughly 0.10% of the company, valued at around $113.8 million, even as the stock remained highly correlated with Bitcoin's volatility.

On Monday, Bitcoin fell under $86,000 while smaller traders accumulated roughly $474 million in buy volume as larger holders offloaded about $2.78 billion in BTC. Onchain and order flow data indicate whales remain dominant on the sell side and short‑term holders are realizing losses, leaving price exposed to potential retests of $83,800 and possibly $80,600.

Bitcoin extended its slide on Monday, trading near $86,000 as the Coinbase Premium Index moved back below zero. The sub-zero reading points to softer U.S. buying interest amid rising volatility, while failed attempts to reclaim $92,000 and derisking in futures add to caution. A retest of the $82K–$84K area remains a risk if sentiment does not improve.

Bitcoin adviser and author Terence Michael cautioned the community after a client who had saved for years lost 1 BTC to a romance-style pig-butchering scam. In a post on X, he described how social engineering prevailed despite multi-signature safeguards and advisory interventions.

On Dec. 15, Bitcoin moved between roughly $88,600 and $89,800 while traders watched transfers from wallets tagged to Wintermute, a narrowing CME futures gap, and a test of rising daily chart support near $89,000. BTC traded about 1.68% lower on the BTC USDT pair, and some analysts warned that a breakdown of this trendline could open the way toward the $80,000 region even as resistance remains clustered around $92,000 to $95,000.

On 15 December 2025, veteran trader Peter Brandt argued that Bitcoin's long-observed parabolic cycle structure may no longer hold as the market matures. He pointed to slower, less sustainable rallies, earlier exhaustion near record highs, and the possibility of a much deeper pullback than many investors expect. In his view, Bitcoin now behaves more like a conventional global asset, with compressed returns and greater uncertainty around halving-driven booms.

American Bitcoin, backed by Eric Trump, has moved ahead of Anthony Pompliano's ProCap Financial in total corporate Bitcoin holdings after adding over 1,000 BTC since the start of December, bringing its stack to 5,044 BTC worth about $443 million. While both firms continue accumulating BTC and the top 100 public companies now hold more than 1.08 million BTC, their share prices and other Bitcoin proxy stocks have come under heavy pressure amid heightened market volatility.
