As an analyst with a background in Bitcoin and blockchain technology, I find the recent findings from BitMEX Research on the centralization of Bitcoin mining to be a cause for concern. The data presented by Alex Bergeron and supported by Mononautical’s tweet reveals that a single entity now controls the coinbase addresses of at least nine mining pools, representing approximately 47% of the total hashrate. This is a significant concentration of power that challenges the very essence of decentralization in Bitcoin.
New research from BitMEX has brought renewed attention to the issue of Bitcoin mining centralization. According to their study, led by analyst Alex Bergeron, over 47% of the Bitcoin network’s hashrate is controlled by a sole entity through its outputs on Coinbase – a concerning level of concentration that hints at the emerging dominance of oligopolies within the Bitcoin mining sector.
As a researcher studying the trends in cryptocurrency mining, I’ve come across Bergeron’s work, which sheds light on the potential role of mining pools in centralization. Bergeron argues that these pools may be driving the trend towards greater centralization by adjusting their payout schemes to reduce variance and make themselves more appealing and competitive.
One individual manages the Coinbase wallets for approximately 9 mining pools, accounting for nearly half of the total mining capacity.
Based on my analysis of the combined rewards output from AntPool, F2Pool, Binance Pool, Braiins, btccom, SECPOOL, and Poolin, it is clear that:

Why The Bitcoin Mining Network Is In A Poor State
The BitMEX Research team delved deeper into these observations by examining the economic consequences of this centralization trend. As stated in their study, approximately $20 million is the estimated capital needed for variance smoothing activities, a relatively insignificant amount compared to the vast size of the Bitcoin mining sector. This revelation raises doubts about the primary cause of centralization being rooted in economic motivations linked to revenue fluctuations.
BitMEX Research developed a model to validate their results by mimicking the functions of a major Bitcoin mining pool. The goal was to reduce payout inconsistencies. Using fundamental probability and financial principles, this simplified model predicts daily mining operation outcomes and evaluates the durability of a reserve fund under various levels of network hashrate involvement.
According to our simulations, a Bitcoin mining operation can stay financially sound for a year if it starts with a reserve of between 300 and 450 Bitcoins, despite unfavorable market conditions. The findings suggest that while larger mining pools with substantial hashrate would necessitate greater funds to keep running, the required capital remains manageable for significant industry players.
Although these financial understandings are important, the repercussions of such control extend far beyond economic intricacies. The possession of almost half the Bitcoin network’s hashrate by a single entity not only infringes upon the decentralized essence that underpins Bitcoin’s core philosophy but also raises significant concerns regarding network security, potential market manipulation, and the authenticity of transaction confirmations.
“The report sparks intense debate among Bitcoin enthusiasts, steering the conversation away from the practical aspects of running massive mining facilities towards deeper questions about the long-term implications of such concentration.”
“Centralization to this extent carries the risk of being both beneficial and detrimental. On one hand, it can lead to improved economic productivity and consistency in mining processes. However, it could also confer excessive control to a select few, threatening the trust and decentralized foundation that underpins Bitcoin,” according to BitMEX Research.
The Community Needs To Act Now
During the ongoing discussion, it emerges that the Bitcoin mining industry requires more than mere economic and functional assessments. There’s a rising clamor for fundamental changes within the sector to address concerns of over-centralization and safeguard the network’s long-term vitality.
As a researcher studying the challenges facing the Bitcoin network, I believe it is crucial for all parties involved – miners, developers, and regulatory bodies – to collaborate in finding solutions that preserve fair competition and safeguard Bitcoin’s decentralized essence.
According to BitMEX Research, the Bitcoin mining network seems to be in a vulnerable state with approximately half of the global mining hashrate’s output being held by a singular entity through Coinbase. This centralization poses a significant issue.
However, the firm also presents a silver lining:
The good news is that the amount of capital required by pool operators to mitigate the effects of random chance might not be as substantial as some assume, possibly ranging from $20 million to $40 million. Consequently, while this luck factor poses a challenge, it may not be the sole critical factor leading to this perceived monopolistic setup in the long term.
At press time, BTC traded at $62,889.
