so stop making new threads and stick your idea's to the single thread. if /when quantum computing comes along, everything and anything encrypted is at risk.

the info on your credit card that is supposedly encrypted
the encryption of secure websites including your bank
governments own email system
enforcement agencies own computer systems
the list goes on.

so the banking systems holding a few trillion per country in a few places and many billions in the many many other countries are at risk more so then bitcoin which has individual "passcodes" per account. rather then 1 encryption "passcode" to secure entire bank databases
