But I'm still wondering the coin who caught as a scam coin but it was listed on the exchange, can you name one of them?
Bitconnect as one of example. That coin got delisted from any of exchange and doesn't has any volume anymore.
As far as I know if there is coin/token who have a fake team and end up with scam they won't ever to listed on the exchange. Their purpose only collected a money from such as an ICO, if the ICO has ended the coin won't be send by the team because they will run away before the ICO project ends.
That's mean the token didn't ever get listed before, and why should a site listed a token which turned to scam?
