🐋 WHALE WATCH : Glassnode data shows 7.12M BTC 35.4% of supply already has public keys visible on the blockchain. At current prices thats over $500B exposed to future quantum attacks. Most Bitcoin addresses reveal their public key the first time you send from them. Any coins left in that address afterward are exposed. Coins sent to it later are exposed too. The fix is simple: move exposed coins to a fresh address. One transaction ends it.
