So what part don't you agree with?? Bitconnect always profited in BCC from the lending system and didn't need to take BCC from new lenders to pay old ones. So it wasn't a ponzi. When someone lent 1BCC for example, by the end of the term the capital release would only cost bitconnect say 0.1BCC if the coin had gone up 10 times in that 8 months or whatever
They would only be paying out less BCC than they took in if the price of BCC kept going up. The price of BCC would only keep going up if people were making new loans at an exponentially increasing rate. That's not sustainable. Eventually they'd be paying out more BCC than they took in, and would end up unable to pay. That's what makes it a Ponzi.
They're cashing in the BTC and paying out BCC in exchange. They will deceive you and think BCC has value. This ponzi scheme is really smart because you won't be pulling out some BTC resources in order to payout those who joined their scheme. Can i pay BCC to buy a pizza? Of course not! You got to convert it first in BTC. And BTC is the one who got the real value than this.
