According to TechFlow, data from CryptoRank and Glassnode reveals that as of May 14, 2025, Bitcoin's illiquid supply, which refers to Bitcoin held long-term with minimal circulation, has exceeded 14 million coins. This accounts for nearly two-thirds of the total mined supply. The data further indicates that in the past 30 days alone, 180,000 Bitcoins have been transferred into dormant wallets with little spending history, reinforcing the market's long-term holding trend. Charts demonstrate a clear positive correlation between illiquid supply and Bitcoin prices since 2019.
