So I have to admit it is sorta interesting to run into your own posts two years later. So they sorta have something working. https://blockdx.co/market-history

That said I also ran into some recent promotion of this exchange. There are many ways to rate or grade projects. Is it a scam? Is it a failed Project? Is it a troubled project started by someone with good intentions? Is it a bad copy of some some working software to try to create another project. Crypto is full of a wide variety of actors and scams. I would not trust Blocknet my research above has forever given me warning about not trusting them.
