Ordinal NFT Inscriptions Drive Bitcoin Transaction Fees Higher as Miners Reap the Benefits

Bitcoin miners are experiencing an unexpected revenue boost in early February 2023 as a new phenomenon takes hold of the network: Ordinal NFT inscriptions. With over 4,600 inscriptions already minted on the Bitcoin blockchain, these digital artifacts are creating fresh demand for block space and driving transaction fees upward at a time when mining economics have been under severe pressure.

TL;DR

• Over 4,600 Ordinal NFT inscriptions minted on Bitcoin by February 4, 2023 — up from roughly 1,600 just days earlier
• Ordinal mints are bidding up transaction fees as they compete for limited block space
• Bitcoin hashrate dropped 7.4% from its all-time high of 297 EH/s due to severe winter storms hitting Texas miners
• Mining hashprice sits at $74.95/PH/day, with BTC-denominated hashprice actually rising 0.45%
• New-gen ASIC prices rose for the second consecutive week, signaling improving market sentiment

What Are Ordinal Inscriptions?

Ordinal NFTs, also known as inscriptions or digital artifacts, represent a new method of publishing non-fungible tokens directly on the Bitcoin blockchain. Unlike traditional NFTs on Ethereum or Solana, Ordinals embed the actual image or content associated with the token on-chain. The system uses an ordering mechanism to number and track each inscription on the Bitcoin network.

The growth has been explosive. From just over 1,600 inscriptions on Thursday, February 2, the count surged past 4,600 by Sunday, February 5 — nearly tripling in a matter of days. This rapid adoption has ignited fierce debate within the Bitcoin community about whether NFT minting is an appropriate use of block space.

Block Space Competition Heats Up

The timing of the Ordinal minting spree is particularly significant for miners. Bitcoin’s hashrate has fallen approximately 7.4% from its all-time high of 297 EH/s, likely due to severe winter storms impacting mining operations across Texas and broader North America. As of February 4, the network hashrate stands at roughly 275 EH/s, a 6.4% decline from the prior week.

With blocks coming in more slowly due to the reduced hashrate — and difficulty holding steady at 39.35 T — the combination of ordinary transaction backlogs and Ordinal minting activity is creating upward pressure on transaction fees. For miners, this is a welcome development. Fee revenue as a percentage of the total block reward has been climbing, supplementing the base subsidy at a time when margins remain thin.

Mining Economics Show Signs of Recovery

Bitcoin’s hashprice — the revenue a miner earns per petahash per day — stands at $74.95/PH/day as of February 4, down just 1.31% from the prior week. In BTC terms, however, hashprice actually increased 0.45% to 0.00323732 BTC/PH/day, reflecting the boost from higher transaction fees driven by Ordinal activity.

At a power cost of $0.07/kWh, profitability for popular mining rigs looks increasingly viable. The Antminer S19 XP generates approximately $5.40 per day, while the Whatsminer M50S+ earns around $4.70 daily. Even older generation machines like the Antminer S19 are turning a modest profit of $1.70 per day.

ASIC Market Sees Rare Price Increase

The Bitcoin mining ASIC market, which has been in a nearly year-long decline, is showing signs of life. New-generation mining rig prices rose to $14.56 per terahash, a 1.6% increase — marking the second consecutive week of gains. Mid-generation machines also saw a modest 1% bump to $9.20 per terahash. Old-generation hardware remained flat at $4.72 per terahash.

This rare upward movement in ASIC prices suggests that buyers are returning to the market, encouraged by Bitcoin’s 44% price rally since New Year’s Day and the corresponding improvement in mining profitability.

Mining Stocks Rally

Publicly traded Bitcoin mining companies have been among the biggest beneficiaries of the recent market recovery. The Crypto Mining Stock Index rose 3.4% over the week ending February 3, though gains were unevenly distributed. CleanSpark led the pack with a remarkable 22.30% gain, followed by Hut 8 at 16.32% and Hive Blockchain at 11.90%. Riot Platforms gained 8.92%, while Marathon Digital actually declined 8.77% over the same period.

Why This Matters

The intersection of Ordinal inscriptions and Bitcoin mining economics represents a fascinating development for the network. For the first time, there is meaningful organic demand for Bitcoin block space beyond simple value transfers — and miners are the direct beneficiaries. Whether Ordinals represent a sustainable new revenue stream or a passing phenomenon remains to be seen, but the early data suggests that Bitcoin’s fee market can support novel use cases that strengthen miner revenue.

With Bitcoin trading around $23,332 and hashrate temporarily suppressed by weather events, the Ordinal-driven fee bump provides a cushion that helps miners maintain operations during a period when many are still recovering from the brutal conditions of 2022. The second consecutive week of rising ASIC prices further confirms that market participants see better days ahead for Bitcoin mining.
