Binance holds 85% of its Bitcoin (CRYPTO: BTC) in quantum-exposed outputs, while Coinbase Global Inc. (NASDAQ:COIN) sits at 5%, according to Glassnode data analyzing which coins are vulnerable to future quantum computer attacks.
6.04M BTC Currently Quantum Exposed At Rest
Something went wrong.
Glassnode identified 6.04 million BTC, or 30.2% of issued supply, as quantum exposed. These coins are vulnerable because their public keys are already visible on the blockchain.
The threat: future quantum computers could potentially crack the private key from a known public key and steal the coins without waiting for the owner to move them.
