Ponzis aren't totally wrong unless you misrepresent what they are, which Bitconnect did.
I personally don't think they are to blame for their lending platform shutting down. In fact, I don't think they were doing anything wrong to begin with. We saw something that resonates as an "old ponzi scheme", people are making shit-tons of money, and then other people are afraid or don't understand bitconnect, ended up bashing and attacking it.
It was a scam, plain and simple.
