If quantum computing breaks Bitcoin hash then it also breaks any other encryption so I can ssh to your server, login to your bank account, change the code in your github repo.

> El Salvador is not recommending Bitcoin and found low interest in actual use.

El Salvador is not a person.

The president of El Salvador is hardcore Bitcoin believer. El Salvador, the country, is stacking as much Bitcoin as they can, despite pressure from IMF that tries (I wonder why?) to stop them.

> Madoff also had a fund that could return very well

Except he didn't. He was lying about returns of his investments and it crashed and burned when the truth came out.

Blockchain is fully transparent. Every Bitcoin transaction ever made is recorded in immutable database and you get to read the full ledger, from the day it was created.

There is no way to lie about Bitcoin transaction. The current price is decided by an auction with millions of participants.

OpenSSH >9.0 has algorithms in place for the post-quantum world:

     * ssh(1), sshd(8): use the hybrid Streamlined NTRU Prime + x25519 key
       exchange method by default ("[e-mail]").
       The NTRU algorithm is believed to resist attacks enabled by future
       quantum computers and is paired with the X25519 ECDH key exchange
       (the previous default) as a backstop against any weaknesses in
       NTRU Prime that may be discovered in the future. The combination
       ensures that the hybrid exchange offers at least as good security
       as the status quo.
