Not only quantum computing is dangerous.

The development of illegal attack techniques on networks and the large finances of cybercrime are much more dangerous.

Although the most famous specialists put quantum computing first.

I don't agree with them.

I agree there are other bigger threats to Bitcoin than quantum computing but what are you hinting to when you say "illegal attacks"?

----------------------------------------------
It's the complexity of machine translation, all attacks are illegal, that's right.

Including attacks on cryptography using quantum computing (using a quantum computer).

And by "more dangerous" attacks, I mean exploiting for criminal purposes the weaknesses of cryptography itself on elliptic curves.

I don't understand it, why one part of people consider it reliable, and officials of special organizations categorically prohibit its use.

I do not understand why there is one cryptography for all of us, it is like household cryptography, and why there is another cryptography for special organizations and government agencies.

I don't understand why for so many years, long before the quantum computer was going to be built, so many serious people and organizations around the world are looking for a replacement for existing encryption methods.

After all, from an attack with quantum computing, it is enough to simply increase the length of the key.

After all the key in AES 256 bits long is not afraid of quantum computers (it is left as a working mechanism on post quantum period) because the method of encryption itself is very successful.

And cryptography on elliptical curves with any key length is not suitable.
And that's with the fact that the key length of even 512,000 bits or more - post quantum cryptography suits everyone!!!

So there's something wrong with ECC?
