If quantum computers get powerful enough, 6.9 million bitcoins are already vulnerable including 1.7 million bitcoins from Satoshi era Ethereum’s 1000 richest accounts can be compromised in less than 9 days! Quantum computers can reverse engineer your private key from your public key in matter of minutes Bitcoin is vulnerable cuz it leaves public key exposed briefly & apparently a powerful quantum computer only needs 9 minutes to find out your private key & fuck you up! Remember it takes 10 min for a bitcoin transaction to get completed! FML
