Why Bitcoin Transaction Fees Fell Despite Strong Market Activity

Summary

The report explains why Bitcoin transaction fees were unusually low during the 2021–2022 period despite price volatility and continued network use. It describes fees as the outcome of competition for limited block space, where users bid for timely confirmation. The central argument is that lower fees reflected more efficient block-space use as well as shifts in transaction demand, rather than simply a lack of economic activity.

The analysis points to wider SegWit adoption, transaction batching, and Lightning Network use as efficiency gains, alongside reduced OP_RETURN activity and changes in miner selling. It uses block fullness, transaction counts, and fee measures to support this account, while noting that fee metrics vary by denomination and that transaction counts can be distorted by data-only transactions. The report treats the causes as overlapping contributors, not a guarantee of permanently low fees; congestion and renewed demand can still raise fees.

Key ideas

• Bitcoin fees rise when users compete for scarce block space through a first-price bidding mechanism.
• SegWit reduces the effective space cost of witness data and expands transaction capacity within the block weight limit.
• Batching multiple payments in one transaction lowers space use and fees per output.
• Changes in OP_RETURN activity and other user behavior also affect transaction counts and block-space demand.
• Low fees during the period analyzed do not imply permanently low fees because congestion can return.
