Totally agree those perspectives mentioned in this article.
Always do you own due diligence.
Quarkchain has lots of red flags and I also asked in their official telegram group, but they just banned me without answering anything.

They even said they are better than Zilliqa. ( Now they said not better or worse lol)
This project is pure-hyped with a vague whitepaper.
Quark's whitepaper even plagiarized other articles without any reference.
( Now they said it was an editor fault lol )
