7.12 million $BTC now have their public key sitting in plain view on-chain.
That's 35.4% of all bitcoin, per Glassnode, or about $530B at $74.5K.
Back in May the number was 6.04 million. So in roughly six months another 1.08 million BTC, around $80B, joined the pile a future quantum computer would try first.
Nobody can break these keys today, and there's no date for when anyone could. The useful part is where the exposure comes from. Some of it is baked in: old pay-to-public-key coins, a big share of them tied to Satoshi, are never going to move. But nearly three quarters of the total is plain address reuse. That's a wallet habit, not a flaw in Bitcoin.
If you've spent from an address and left coins sitting on it, sending them to a fresh address ends that exposure. One transaction and you're out of the count.
