$BTC
4.33 million BTC are sitting in exposed addresses
Vitalik just issued a warning
And these people still haven’t even changed their wallets?
Damn
Guys
Some people really aren’t afraid of dying
4.33 million BTC
20.6% of the total supply
are sitting in reused addresses
At $86,000 each
that’s worth about $370 billion
These addresses have each initiated at least one transaction
Their ECDSA public keys have long been exposed on-chain
What does address reuse mean?
A regular wallet should use a new address
whenever it receives money
for privacy
Reusing an address means using the same address over and over to receive and send coins
Once a transaction happens
the public key is revealed directly
Your coins aren’t at risk right away
but it creates a long-term vulnerability
Just yesterday, Vitalik issued a warning
AI could significantly weaken lattice cryptography within two years
ECDSA could also be cracked faster than expected
And today, the data is right in our faces
Once you’ve used your wallet address
your public key is permanently etched on-chain
Hackers may not be able to do anything to you now
but that doesn’t mean they won’t be able to in two years
Your privacy is basically out in the open
If you keep sending money from the same address
everyone on-chain can connect all your funds and transaction history
It’s easy to figure out how much you hold and how you trade
If elliptic curves can be cracked in the future
then BTC with already-exposed public keys
will be among the first to take the hit
So, guys
we small-time retail investors
may not have much money
but we should still try to make it a habit
to use a new address every time we receive funds
Don’t keep using the same address to receive coins
Protect your on-chain privacy
If you have a large balance stored in an old address
you can also migrate it to a new address in batches
to reduce long-term risk
