I dont think its a ponzi scheme but the way steem was and continues to be distributed may leave the platform open to major manipulation. Steemit is what it claims to be... a social network where users can get paid to blog. It never claimed to be anything else. This article focused on BTS and not steemit so I think you may have missed the point. Argue why BTS is better or worse from a tech standpoint when compared to other cryptos and then we would be on topic and have a good conversation going.
