BIS Study Finds Bitcoin On-Chain Transfer Estimates Can Vary Sixfold
Researchers at the Bank for International Settlements found that Bitcoin on-chain transfer volume estimates can diverge by as much as sixfold depending on measurement methodology. Contract proliferation and cross-chain stablecoin activity introduce noise into raw transaction counts, complicating efforts to assess genuine economic activity.

Measurement Variance Across Bitcoin
A BIS working paper documented significant discrepancies in how Bitcoin on-chain transfer volumes are calculated and reported. Depending on the methodology applied, estimates for the same period can vary by up to sixfold, according to the researchers. This divergence arises from differing definitions of what constitutes a meaningful transaction and how to filter out custodial or internal transfers.
Why Raw Transaction Counts Mislead
The BIS identified two primary sources of noise in on-chain activity figures. Contract proliferation — the growing number of smart contract interactions and token issuances on Bitcoin — inflates transaction counts without necessarily reflecting economic utility. Separately, cross-chain stablecoin use, where USD-pegged tokens move between networks via bridges and wrapped versions, adds volume to raw tallies while potentially counting the same underlying economic transfer multiple times across different chains.
The researchers noted that Ethereum and stablecoin data face analogous measurement gaps, suggesting the problem extends beyond Bitcoin to the broader ecosystem. The implication is that widely-cited on-chain volume figures, without methodological transparency, may substantially overstate or understate the true economic activity they purport to measure.
Why It Matters
For Traders
On-chain volume metrics used to gauge Bitcoin liquidity and market health may be significantly more or less reliable than commonly assumed, affecting trend-following strategies.
For Investors
Sixfold measurement variance undermines data-driven macroeconomic models that rely on on-chain metrics to infer adoption or real economic throughput in crypto networks.
For Builders
Protocol developers building analytics or risk models atop chain data should explicitly document their transaction filtering and counting methodology to signal reliability to downstream users.
