Maybe you can address this in a future video stream but someone commented that Bitconnect is economically sustainable because it has an internal exchange. The bot could be similar to the bots we have in the Steemit internal exchange. The rise of BTC/BCC and the fact that Bitconnect could be building an exchange could explain how Bitconnect can maintain sustainability for years.

But my math is not good enough to say for sure how much money a central exchange can make per year or whether it is enough. Could they not just add more tokens to the exchange and become like Bittrex? They seem to have a lot of options so the loans might just be to provide for a liquidity pool and then maybe the interest makes sense, at least for now.

How much volume does their exchange get? That would answer some questions because it would reveal how profitable their exchange is. $26,985,000 over the last 24hrs. If Bitconnect takes the path of becoming the next Bittrex or Coinbase then it all would make sense. If Bitconnect does evolve into something useful like an exchange then it changes crypto as we know it and could become a new model for raising funds.

There are concerns if someone compounds over and over until like one person on Youtube they are earning over 1 million a week. At a certain point they will not be able to cash out. Would Bitconnect be able to limit the amount of loans a single account takes or limit the compounding so one greedy person doesn't break the bank? If they do that then Bitconnect in theory could last a long long time.
