If they are still open and trading then most probably is not a scam but it is cobinhood's fault to not bring liquidity to the exchange. They must incentivize market makers to come to cobinhood. As we can see they don't have many coins trading there but the exchange has a nice UI. I have noticed that their orders books look buggy or is it just me? Can anyone tell me where can I find the whitepaper so I can see what are their tokenomics?
