Quantum does not mean Bitcoin instantly breaks.
Even if ECDSA becomes attackable, stealing coins still requires targeting exposed public keys with massive resources.
Bitcoin can migrate to quantum-resistant signatures.
Long-term risk? Yes.
Instant chain drain? No.
I firmly believe that leaving them there was intentional. A cracked encryption will serves as proof of hard work, considering the significant amount of time required per #bitcoin key. Satoshi left many of them behind.
I appreciate the enlightenment, @Meta. I am now ready to take action! If you don't own any #bitcoin, get ready for your bank account to be blocked in the next covid like Covid scam!
