Elliptic curve signature ECC will be cracked by quantum computers,

and the private key is obtained after cracking the public key.

Elliptic curve signature is widely used in the entire currency circle.

Governments and corporations have begun to abandon elliptic curve signature ECC!

It's time for cryptocurrency to abandon ECC! "

Put another way:

ECC lets a Quantum Computer derive a Private Key from a Public Key. It is widely used across the entire public blockchain space.

Governments and corporations are already abandoning it.

It's time cryptocurrency did the same.
