Bitcoin miners are under increasing pressure as their reserves have dropped to 1.806 million BTC by December 23, 2025, according to CryptoQuant. This decline, particularly noticeable in late 2025, indicates that miners are selling more Bitcoin to cover operational costs due to weakening prices. Daily BTC inflows to miners have fallen to multi-month lows, ranging between 400 and 700 BTC. Despite Bitcoin's price falling to $88,000, mining difficulty remains near an all-time high of 660Z, exacerbating the financial strain on miners. If Bitcoin prices remain below $90,000, further sales or relocations by miners could increase, potentially adding more supply pressure to the market. Meanwhile, traders are closely monitoring altcoins for any shifts in market sentiment.
