âđš 4.33M Bitcoin is Sitting in "Exposed" Addresses. Are Your Funds Safe?
âA staggering 4.33 Million $BTC â roughly 21.5% of the total circulating supply â is currently sitting in reused Bitcoin addresses, according to recent Glassnode data.
âWhen you combine address reuse with legacy formats (like early Satoshi-era P2PK addresses), the total supply with exposed public keys climbs to 6.26 Million BTC (31.2%).
âWhy does this matter, and should you be worried? Letâs break it down đ
âđ What Actually Happens When You Reuse an Address?
âBitcoin was designed with privacy and security in mind â generating a fresh address for every incoming transaction is free and seamless.
âWhen an address receives BTC, its public key remains hidden behind a hash (the wallet address). But the moment you spend or send BTC from that address, your public key is permanently revealed on the public blockchain.
âIf you continue to send funds to that same address:
âPrivacy vanishes: Blockchain analytics companies can easily trace your walletâs full history and balance.
âSecurity exposure: Exposed public keys reduce security margins against future threat vectors (like post-quantum cryptographic challenges).
âđ The Numbers At A Glance
â4.33M BTC (21.5%): Held in operational reused addresses.
â1.71M BTC: Sitting in legacy P2PK scripts (~1.10M BTC belongs to Satoshi Nakamoto).
â1.79M BTC: Held across major exchanges under visible public keys.
âđĄïž How to Protect Your Wallet
âUse HD (Hierarchical Deterministic) Wallets: Modern non-custodial wallets automatically generate a brand-new receive address every time.
âAvoid Manual Re-use: Never send funds back to an old deposit address saved in your exchange history or contacts.
âExchange Deposits: Always double-check and refresh your deposit address on platforms like Binance before transferring.

Do you regularly use a fresh address for every transaction, or do you still reuse old ones out of convenience?
