Fractal Bitcoin is emerging as a notable sidechain-style mining opportunity for Bitcoin miners, with new data showing that the network is now leveraging roughly 226.19 exahash per second (EH/s) of Bitcoin hashrate through merged mining. On top of that, another 18.1 EH/s from permissionless mining is helping support network activity. At a time when margins from mining BTC alone have been under pressure, the added rewards from Fractal Bitcoin are giving mining pools a new source of income.
Bitcoin Hashrate Is Powering Fractal Bitcoin’s Expansion
According to the reported onchain metrics, Fractal Bitcoin has produced a total of 40,354 blocks so far, while approximately 2,068,925 FB tokens are currently in circulation. With FB priced at $12.91, the token’s market capitalization stands at about $26.8 million. That places it at No. 674 by market cap among more than 10,000 crypto assets.
The network’s merged-mining model appears to be the central driver behind its rapid operational growth. Of the 226.19 EH/s attributed to merged mining, 103.4 EH/s is linked to unknown Bitcoin miners. Among identified mining participants, Antpool is contributing 82.34 EH/s to Fractal Bitcoin, out of the 170.74 EH/s it allocates to the Bitcoin network overall. F2pool contributes 25.48 EH/s, while Spiderpool adds 7.72 EH/s.
Permissionless mining participants include F2pool, Spiderpool, Maxipool, Moonx, Solo Fractal, and Fairpool. Taken together, these figures suggest that Fractal Bitcoin has built meaningful traction by piggybacking on Bitcoin’s mining ecosystem rather than competing directly with it for standalone hashrate.
FB’s Price Volatility Contrasts With Strong Mining Participation
While the network has attracted substantial computational support, the price action of its native token has been far more unstable. FB reached an all-time high of $38.80 on September 15, 2024, but only six days later it had fallen 61.9% from that peak to $12.91. The sharp reversal highlights the speculative nature of newer mining-linked assets, especially those still early in their distribution cycle.
In the last 24 hours, FB recorded about $18.79 million in global trading volume. Although that is a meaningful figure relative to its market cap, it represented only 0.03523% of the broader crypto market’s total daily volume of $53.352 billion. This suggests that while the token is actively traded, it remains a relatively small asset in the wider digital asset landscape.
Wallet Concentration Adds Another Layer of Risk
Another point likely to attract scrutiny is the concentration of FB holdings. Data cited in the report shows that the top five wallets hold 32.3% of the roughly 2 million FB currently in circulation. In total, those addresses control 668,631.54 FB. The single largest wallet alone accounts for 15.7% of circulating supply.
For a token with a relatively small current float, this level of concentration can become a significant market factor. Large holders may influence liquidity conditions, increase perceived sell-side risk, or shape sentiment in a way that would be less visible in more broadly distributed assets. Even if network participation continues to strengthen, concentrated ownership may remain a key variable for investors watching FB’s market behavior.
Merged Mining Is Delivering Meaningful Supplemental Income
From the miners’ perspective, the economics are easier to understand. Each Fractal Bitcoin block is currently generating between 32 and 34.5 FB, which translates to just under $495 per block at current prices. For mining pools already securing Bitcoin, those rewards represent incremental revenue earned alongside BTC mining rather than in place of it.
The report offers specific examples of how that value is accumulating. One wallet controlled by F2pool reportedly holds 30,128.73 FB, valued at around $388,000. Another F2pool address holds 10,318.35 FB, worth about $150,000. Meanwhile, one of Antpool’s coinbase reward addresses contains 22,922.6 FB, equivalent to roughly $335,000.
In an environment where Bitcoin mining profitability has tightened, these sidechain-linked rewards can make a practical difference. The article notes that miners earned more than $500,000 in under two weeks through this additional stream of income. For major pools, that makes Fractal Bitcoin more than a technical experiment—it becomes a potentially useful financial supplement.
Supply Expansion Could Shape Long-Term Valuation
Still, the current token supply tells only part of the story. Although around 2 million FB are circulating today, the token’s maximum supply is 200 million FB. Using the current market price, the project’s fully diluted valuation would rise to approximately $1.3 billion. That creates a significant gap between current market capitalization and long-term dilution assumptions.
This matters because early traction in mining participation does not automatically translate into durable token value. Fractal Bitcoin may continue to attract hashrate if merged mining remains profitable, but sustaining the market price of FB will likely depend on broader trading demand, token distribution, and confidence in the network’s long-term utility.
For now, Fractal Bitcoin presents a mixed picture: a sidechain supported by substantial Bitcoin-linked hashrate, a token that recently experienced both a breakout and a steep pullback, and a mining model that is already generating measurable incremental revenue for large pools. Whether that combination evolves into a durable ecosystem or remains a short-lived yield opportunity will depend on how the network balances growth, distribution, and market stability in the months ahead.
