Wow so way off base. First off, the coins are not sustainable as there is nothing driving them. Bitconnect will need new investors to be sustainable and who will have any confidence in them? Yes they are a classic Ponzi. Ponzis always have good intentions, Ponzis have incredible returns like Bitconnect. Ponzis thrive under good market conditions because new money keeps flowing in, like Bitconnect, Ponzis, have no real logic or numbers behind them, they feed off of good economic opportunities, such as the price of Bitcoin going up. The only way into Bitconnect was by investing with Bitcoin. As long as Bitcoin kept going up, they were sustainable. As soon as the market crashed, Bitconnect had nothing, no trading bot, no true sustainability so they closed their doors. If they were not a Ponzi, they would have paid back in fiat or Bitcoin, but they chose to pay in BCC, a crypto they knew was worthless. Typical Ponzi. T
