Hello, community! )) Do anyone know about post-quantum altcoins? I’ve read here https://dapcash.org/quantum-apocalypse that all coins will die soon… How do you think guys? Maybe it is a fake? Do anyone take it seriously?

Pay close attention to a project team. If a team comprise too many managers, advisors, and marketers it could mean those founders are primarily concerned about the image of a project. Don't get fooled by these decorations. In a decent blockchain project, the main role is played by developers”. Obviously, someone from techies wrote this, the hater of managers and marketers :-) and really useful thought of the size of a hard cap. A few more interesting arguments about how to choose a new coin for investment here https://dapcash.org/choose-altcoins-for-investment/

I read the topic carefully. Of course, you can condemn the author and those who support him, for unreasonable panic. But here, for example, is another objective and independent scientific opinion about the quantum vulnerability of the blockchain:   

“Quantum computers put blockchain security at risk. Bitcoin and other cryptocurrencies will founder unless they integrate quantum technologies, warn Aleksey K. Fedorov, Evgeniy O. Kiktenko and Alexander I. Lvovsky.”

“By 2025, up to 10% of global gross domestic product is likely to be stored on blockchains1. A blockchain is a digital tool that uses cryptography techniques to protect information from unauthorized changes. It lies at the root of the Bitcoin cryptocurrency2. Blockchain-related products are used everywhere from finance and manufacturing to health care, in a market worth more than US$150 billion.
When information is money, data security, transparency and accountability are crucial.
The blockchain business needs to update its existing software to use one-way cryptographic functions that are equally hard to reverse using conventional or quantum computers9. Until these post-quantum solutions are established or standardized, platforms must be flexible and capable of changing cryptographic algorithms on the fly.”

Basically, scientists write about all the same as in the article referred to by the author of the topic: https://dapcash.org/quantum-apocalypse  Only a little less emotions:-)
