Interesting subject here, so I decided to post.

I have been studying Bitcoin Taproot addresses and it seems or not because I have read YES and NO that is not possible to hide public key until first transaction because all Taproot addresses expose it naturally (if someone can explain/clarify it, I would appreciate).

I read some comments, about that is not important and pubkeys should be public, bla bla bla...

Satoshi Nakamoto use to say to use the address only one time for max security and there is a reason for that for sure.

Many ppl is speaking that with a quantic attack many bitcoin would be taken and bitcoin would go to zero if someone have enough powerful quantic computer.

I disagree with that, imagine there is a quantic computer that can brake it in 1 year, all addresses already transacted at least 1 year would be exposed, but all the other would be safe and if someone someday have access to a quantic with power to brake bitcoin for sure he will not start to stole every bitcoins he can and make market go down, of course they would be subtil and just make surgical stoles, the type of attacks the owner will complaint and everybody will think he just was hacked by some APP or he is dumb, nobody will believe that it was a quantic attack (same as when in 2nd WW allies made with german Enigma machine, they didn't refute all german steps to don't put on check the important advantage they already have.)

In a time that many ppl is talking about possibility of future quantic attacks for bitcoin, Satoshi already have made the 1st step against quantic attack hiding the public key until first and possible only move if we just move the exchange to a new address.

So, if Taproot addresses always expose the public key, I don't know about you, but I would not use them to save my bitcoins in a cold wallet, maybe for another applications could be good enough, but not for cold wallets.

What you think about it?
