Binance (CRYPTO: BNB) founder Changpeng “CZ” Zhao estimated on Saturday that 10–20% of all Bitcoin (CRYPTO: BTC) that have already been mined are effectively gone forever.
Permanetly Lost BTC?
CZ noted in an X post that 20.07 million BTC have already been mined, with only 4.4% of the remaining supply remaining to enter circulation.
“I’d estimate 10-20% of existing Bitcoins are lost/stuck/unrecoverable,” he added, which translates to roughly 2–4 million BTC.
Given that Bitcoin’s total supply is capped and the usable supply continues to decrease as coins are permanently lost, CZ deemed Bitcoin a “deflationary asset.”
Satoshi’s BTC Also Inaccessible?
CZ’s figures were largely in line with other analysts. BitGo estimates 2.3–4 million BTC, or about 11–18% of the 21 million supply cap.
