At the beginning of December, a Bitcoin miner wallet that had been dormant for over 15 years was awakened under record mining pressure, transferring 50 Bitcoins, worth approximately $4.33 million, to an external address. The on-chain tracking platform Lookonchain confirmed that the wallet belonged to the "Satoshi Nakamoto era," and this transfer became one of the oldest Bitcoin movements in recent years.

Miner reserve data shows that Bitcoin miners have sold approximately 300,000 Bitcoins over the past two years, with miner reserves continuously declining, reflecting ongoing selling pressure in the market. Mining difficulty has risen to a historic high of 149.30 trillion hashes, and hash rate revenue has decreased from around $55/PH/s in the third quarter of 2025 to $35/PH/s in November, below the average cost of major mining companies at $44/PH/s. Even with the use of next-generation mining machines, the payback period exceeds 1,000 days, far exceeding the countdown to the next Bitcoin halving.
