Hi steemians.
Given that you are talking about crypto currency exchanges, I assume that you are not newbies and can recognize #scams. But there are members of our community that are not aware of Ponzis, HYPIs etc. I find a scam site called CryptoClone and write an article about it. Would you read it, comment, resteem and make it viral. Hope nobody "invested" here.
