Washington state has emerged as the leader in Bitcoin adoption among U.S. states, according to a recent study by SmartAsset. The report revealed that 2.43% of tax returns filed in 2022 indicated some form of cryptocurrency activity, translating to approximately 91,310 households reporting their involvement to the IRS.
Following Washington, Utah ranked a close second with a participation rate of 2.36% in IRS-reported crypto activities. Notably, California, Colorado, and New Jersey completed the top five states for cryptocurrency involvement among taxpayers.
Conversely, West Virginia was identified as having the lowest rate of crypto activity, with only 0.84% of its tax returns indicating any engagement with digital currencies. Mississippi followed closely with a participation rate of 0.95%.
In a separate analysis conducted by CoinGecko in May 2026, website traffic metrics indicated that California was the dominant state for interest in Bitcoin and Ethereum, accounting for a staggering 43% of all U.S. web traffic related to these cryptocurrencies, attributed a perfect indexed score of 100. Other states, including Illinois, New York, Florida, and Washington, trailed behind in this ranking, underscoring California’s substantial lead.
A noteworthy income disparity has surfaced in crypto participation rates. Households earning $500,000 or more annually reported a substantial participation rate of 5.55%. In stark contrast, this figure dropped to just 1.27% for households earning between $1 and $75,000, highlighting the correlation between income levels and cryptocurrency involvement.
In response to the growing interest and potential of cryptocurrencies, over 30 U.S. states had introduced legislation designed to establish strategic Bitcoin reserves by mid-2026. New Hampshire and Arizona were pioneers in this legislative landscape, introducing Bitcoin reserve laws back in 2025.
On the global front, the United States holds the second position in overall crypto adoption indices, sitting just behind India, as indicated by data from Chainalysis and TRM Labs. This data reflects the rising prominence of cryptocurrencies not only as investment vehicles but also as a significant component of state-level economic strategies.
