Most #BTC with a visible public key is exposed through address reuse, and that part has been growing.
The balance in reused addresses rose from 3.79M to 4.33M BTC over the past year, and now covers 21.5% of circulating supply.
Replying to @n3ocortex
Address reuse accounts for 4.33M BTC: the address has already spent, so its key is public. Moving those coins to a fresh address ends the exposure.
The other 1.94M BTC are exposed by script type: 1.71M in P2PK, of which 1.10M is attributed to Satoshi, and 222K in Taproot.
