My research indicates Cardano will be Quantum resistant.
Please add to the list:
Projects that are not quantum resistant will not have good futures: opinion
At least it's much better for you to show the result of your research about what makes cardano will be a quantum-resistant coin.
AFAIK, all about quantum computer is only speculation only and some big companies like google are still developing it right now.
I don't even think a computer that worth millions of dollars must be used to mine crypto to get a little penny.
I'm waiting for you to publish what aspects that make you feel you can call cardano will be quantum-resistant.
Something like AES that some people argued if that can give protection from quantum computer.
