#比特币重复使用地址持有433万枚btc
Who would have thought that after all these years of Bitcoin’s development, an inconspicuous habit could have left security vulnerabilities in BTC worth hundreds of billions of dollars? 😂
According to Glassnode data, the public keys of around 4.33 million $BTC have become publicly visible due to address reuse, accounting for about 21.5% of the circulating supply—up 14.2% from a year ago.
If you also count other types of addresses with publicly visible public keys, the total could be as high as 6.26 million bitcoins.
Many people may not understand what this means.
Put simply, the public keys of some Bitcoin addresses aren’t directly exposed until funds have been spent from them. But as soon as you send BTC from one of these addresses, its public key is usually revealed on the blockchain.
If you keep reusing that address, you’re effectively giving up an extra layer of protection.
For now, a publicly visible public key doesn’t mean your coins can be stolen outright. The real concern is future quantum computers.
If quantum computing advances to the point where it can crack today’s elliptic curve digital signatures, bitcoins whose public keys were exposed in advance could be among the first at risk.
The wildest part is that people spend every day thinking about how to guard against hackers, phishing, and exchange collapses, yet never consider that repeatedly using the same receiving address could also leave them exposed in the long term.
In the past, all you had to worry about when holding coins was losing your seed phrase. Now you also have to worry about future quantum computers digging up the past. 😭
