The supply of Bitcoin on centralized exchanges has plummeted to its lowest level since 2018, according to Coinomedia. This trend highlights a significant move by investors towards cold storage and self-custody, indicating a preference for long-term holding. The shift is driven by increased interest in Bitcoin as a store of value and concerns over centralized platforms following recent regulatory actions and exchange failures. Analysts suggest that this reduction in exchange-held Bitcoin could decrease selling pressure, potentially supporting Bitcoin's price during periods of high demand. The move to cold storage reflects a growing confidence in Bitcoin's long-term value proposition among investors.
