The founder of Ethereum made that opinion based on nothing more than the returns. Ethereum went up over 7000% and no stock ever does that. Evidence of a Ponzi right? Same evidence Vitalik used. The truth is, Bitconnect is a blockchain just like Ethereum. Ethereum is a better technology, more decentralized, but also profitable for people who held, but for people buying at the top of the bubble, they might see the price crash in the future and call it a Ponzi.

So it's a matter of perspective. A person who became a millionaire from Bitconnect likely will not think their Ponzi is a Ponzi, just like a person who became a millionaire from holding Ethereum tokens might not see their Ponzi as a Ponzi. To people holding fiat these are all Ponzis which is why ICOs are banned in some places and crypto is banned in Russia.

Let me paint the picture. In Ethereum, Steem, Bitcoin, the large holders are at the top of the 'pyramid'. In Bitconnect, the large holders in BCC are also at the top of the 'pyramid'. The difference is in who earned the tokens and how. In Steem the top of the pyramid earned it blogginng or mining or buying early on. In Bitconnect it is earned primarily by promoters, marketers, and people who gave out loans early on. In Ethereum it is earned primarily by programmers, or people who bought in early on.

To anyone buying in now, it is an obvious pyramid because the people at the top of the pyramid need to sell to someone right? Who do you think that will be?
