Quantum computation is irrelevent to the common internet of things we all use, they work on different metrics...

Quantum computing may never come to be a reality, its still just an unproven theory. Bitcoin can't be cracked, it is impossible for any address to be brute forced unless there was a flaw in the key generation.
The one who found the vulnerability in secp256k1 will never share with you in this forum. Just you quote the words of those that it is not possible! But experts in the field of cryptography have a different opinion.
