Bitcoin Hashprice Surges 10% as Miners Collect $337 Million in Weekly Block Rewards

Bitcoin miners celebrate a resurgent week as hashprice climbs above $55 per petahash per day, fueled by a 6.26% price rally that pushes BTC back above $102,000. The mining ecosystem shows signs of robust health heading into the second half of May 2025, with block rewards, transaction fees, and mining stock valuations all trending upward in a synchronized bullish signal.

TL;DR

• Bitcoin hashprice reaches $55.17 per PH/s/day, a 10.16% weekly increase
• Miners collect approximately 3,357 BTC (~$337 million) in block rewards over the past week
• Network hashrate registers 890 EH/s on the 7-day SMA, with difficulty decreasing 3.34%
• Mining stock index rises 10.38%, led by Bitdeer Technologies at +34.22%
• Bitcoin Core OP_RETURN controversy sparks debate over blockchain data storage policy

Hashprice Recovery Gains Momentum

Bitcoin USD hashprice increases by 10.16% over the past week, moving from $50.08 to $55.17 per PH/s/day, according to data from Hashrate Index. The BTC-denominated hashprice also ticks upward, gaining 1.65% to reach 0.00054112 BTC per PH/s/day. This recovery brings hashprice close to breakeven levels for many mining operations, depending on their electricity costs and machine efficiency.

The forward market paints a moderately optimistic picture as well, with the hashrate forward curve pricing in an average hashprice of $52.07 or 0.00049 BTC over the next six months. This suggests that market participants expect the current momentum to persist, albeit at slightly lower levels than the spot market.

Miner Revenue and Fee Dynamics

Over the past week, miners collect a total of approximately 3,357 BTC in block rewards, equivalent to roughly $337 million at current prices. Transaction fees constitute 1.14% of total block rewards, totaling 38 BTC or approximately $3.84 million. While fee revenue remains a small fraction of total miner income, the average fee per block per day rises 32% week-over-week from 0.0345 BTC to 0.0455 BTC.

A notable fee spike occurs earlier on May 12, temporarily boosting BTC hashprice for operators hashing at the time. Despite the short-term excitement, fee projection models remain bearish — the ARMA model estimates 0.05 BTC per block per day while the VAR model forecasts 0.06 BTC per block per day for the coming week.

Network Hashrate and Difficulty

The Bitcoin network hashrate registers a slight decline, with the 7-day simple moving average falling 2.20% from 910 EH/s to 890 EH/s. The 30-day SMA stands at 881 EH/s, indicating that the longer-term trend remains stable. The most recent difficulty adjustment on May 3 decreased network difficulty by 3.34% to 119.12T, reflecting the slightly reduced hashrate.

Blocks are found at an average time of approximately 9 minutes and 34 seconds over the past 24 hours, significantly faster than the 10-minute target. This suggests that the upcoming difficulty adjustment, expected around May 16, will likely increase difficulty by an estimated 4.50%.

Mining Stocks Rally

Publicly traded Bitcoin mining companies enjoy a strong week across the board. The Bitcoin Mining Stock Index advances 10.38%, mirroring Bitcoin’s own price appreciation. Bitdeer Technologies (BTDR) leads the pack with a remarkable 34.22% gain to $14.12, reaching a market capitalization of $2.90 billion. Bitfarms (BITF) also performs well, climbing 8.00% to $1.08.

The correlation between Bitcoin price and mining stock performance remains tight, but the outsized gains in some names suggest that investors are pricing in improved profitability at higher Bitcoin levels. With hashprice approaching breakeven for many operators, any sustained Bitcoin price increase above $105,000 could trigger significant margin expansion for efficient miners.

Bitcoin Core OP_RETURN Controversy

While mining economics dominate the headlines, a brewing controversy within the Bitcoin development community adds another layer of complexity. Bitcoin Core announces that its next update will relay and mine transactions with OP_RETURN outputs exceeding the longstanding 80-byte cap. The original limit, designed to discourage arbitrary data storage on the blockchain, now faces reconsideration as large data inscriptions already occur on the network regardless of the restriction.

The decision splits the community. Proponents argue that the change aligns node software with actual network usage, while critics warn about increased costs of running full nodes due to “chain bloat” and a departure from Bitcoin’s primary purpose as a financial tool. The debate echoes previous philosophical battles over block size and Bitcoin’s fundamental identity.

Why This Matters

The confluence of rising hashprice, strong miner revenue, and bullish mining stock performance paints a picture of an industry in recovery mode after the challenges of early 2025. With Bitcoin approaching its all-time high of $109,225, miners find themselves in an increasingly comfortable position — particularly those who maintained operations through leaner months.

The upcoming difficulty adjustment will test whether the current hashrate levels are sustainable. If the estimated 4.50% increase materializes, it signals that new mining capacity continues to come online despite recent hashrate fluctuations. For investors watching the mining sector, the current environment offers a rare window where both Bitcoin price appreciation and improving mining economics align.
