BIS paper finds major gap in Bitcoin onchain transfer estimates

A working paper published by the Bank for International Settlements (BIS) has revealed significant discrepancies in cryptocurrency onchain metrics, warning that widely cited indicators often obscure actual economic activity. Analyzing over 100 billion blockchain records across Bitcoin, Ethereum, and Tron, the study found that estimates of Bitcoin onchain transfer values can vary by as much as sixfold depending on measurement methods, particularly regarding how change outputs and transfers back to senders are treated. The research also underscored broader measurement challenges across the crypto sector. Bitcoin's traditional market capitalization has at times been up to four times higher than its realized capitalization. Furthermore, interpreting smart contracts on Ethereum remains opaque, with roughly 54 million out of 67.5 million active contracts unclassified. Stablecoin utility also differed substantially across networks, with USDT on Ethereum heavily tied to DeFi while USDT on Tron acted primarily as a payment mechanism and store of value. BIS researchers concluded that onchain metrics should be regarded as noisy approximations rather than precise economic indicators. Industry data mirrors this disparity, with Visa's analytics dashboard reflecting $6.4 trillion in unadjusted 30-day stablecoin volume compared to just $313.1 billion in adjusted volume.
