Lost Bitcoin Total Market Size

Professional research indicates about 20% of all Bitcoin currently distributed, has been ‘lost’. By lost we mean owners believe it is lost because they no longer have access to either their wallet by losing their passphrase or seedphrase. Or the private key associated with the Bitcoin.

Chainalysis, a research firm that analyzes activity across different cryptocurrency markets, estimates that between 2.78 and 3.79 million, or between 17 and 23 percent of all bitcoins have been lost.
