What to know:
- JPMorgan said the Bitcoin network hashrate fell for a second straight month in December, signaling easing competition among miners.
- Mining profitability continued to slide, with block reward revenue per exahash hitting a record low, down 32% year over year, alongside weaker gross profits.
- Despite weakness last month, U.S.-listed bitcoin miners and data center operators posted strong gains in 2025, with the group’s market cap up 73% for the year.
The Bitcoin network hashrate, a metric measuring mining competition, declined for a second consecutive month in December, according to a report released by Wall Street giant JPMorgan (JPM) on Monday.
"The monthly average network hashrate, a proxy for industry competition, declined 30 EH/s (-3%) m/m to an average of 1,045 EH/s in December," analysts Reginald Smith and Charles Pearce wrote.

The hashrate refers to the total combined computational power used to mine and process transactions on a proof-of-work blockchain, and is measured in exahashes per second.
Despite the lower competition for the miners, mining profitability also fell. The analysts estimated that miners earned an average of $38,700 per EH/s in daily block reward revenue last month, "down 7% from November and 32% y/y, representing the lowest level on record." Daily block reward gross profit also declined last month, dropping 9% to $17,100 per EH/s, the report said.
While the bank didn't go into detail about why mining profitability is falling, lower bitcoin prices since October have likely added to the margin squeeze for miners who are already feeling the pain from the most recent halving and higher energy prices.
Although it's not all doom-and-gloom. The combined market cap of the 14 U.S.-listed bitcoin miners and data center operators that the bank tracks rose to $48 billion by the end of 2025, up 73% for the year. Hut 8 (HUT) was the best performer of the group last month with a 2% gain, while CleanSpark (CLSK) underperformed with a 33% decline.
While only two of the companies outperformed bitcoin in December, 9 of the 14 beat the largest cryptocurrency over the course of the year, led by IREN (IREN) and Cipher Mining (CIFR), the report added.

KuCoin captured a record share of centralised exchange volume in 2025, with more than $1.25tn traded as its volumes grew faster than the wider crypto market.
What to know:
- KuCoin recorded over $1.25 trillion in total trading volume in 2025, equivalent to an average of roughly $114 billion per month, marking its strongest year on record.
- This performance translated into an all-time high share of centralised exchange volume, as KuCoin’s activity expanded faster than aggregate CEX volumes, which slowed during periods of lower market volatility.
- Spot and derivatives volumes were evenly split, each exceeding $500 billion for the year, signalling broad-based usage rather than reliance on a single product line.
- Altcoins accounted for the majority of trading activity, reinforcing KuCoin’s role as a primary liquidity venue beyond BTC and ETH at a time when majors saw more muted turnover.
- Even as overall crypto volumes softened mid-year, KuCoin maintained elevated baseline activity, indicating structurally higher user engagement rather than short-lived volume spikes.
