According to Odaily Planet Daily, as of May 2025, approximately 19.6 million Bitcoins have been mined, representing 93.3% of the total supply of 21 million Bitcoins. However, companies like Chainalysis and Glassnode estimate that approximately 3 million to 3.8 million BTC (approximately 14%-18% of the total supply) may be lost or remain unchanged. This includes some high-profile dormant addresses, such as Satoshi Nakamoto's address, which holds over 1.1 million BTC. (Cointelegraph)
