Didn't know ANS is working on that. Nice, I happen to own a few. As far as I know they're considered being the ETH of China. And as China has the policy to only use Chinese products instead of the western counterpart this ANS mightbe up to a surge.
Anyway, a few cryptocurrencies are mentioned when it comes to quantum resistance. First and foremost probably the Quantum Resistand Ledger, but also IOTA. Even ETH is mentioned to have to built in option to upgrade the algo to quantum resistant when available. And probably many more as well. So, for now I wouldn't worry about it too much. It will be implemented when necessary. As the tech is easy to be copied I also would not expect the current projects to be the most profitable ones to invest in. A crypto needs much more than just features in order to be a financially successful investment.
Most recently I bought COEVAL. Monkey Capital seems to be quite serious about their project. So far it's well into profit and if the predictions of mainstream media is even remotely accurate, then we'll see a huge rise coming :)
