Bitconnect looked like a pyramid scheme from early on, and it had a ton of warning signs. If you missed the fact even a ton of people on youtube told everyone that bit connect was a scam, so you didn't even need to notice it yourself.
I want to know why people got involved while knowing that it was a HORRIBLE scam from early on?
Well I guess their community had a great manager and he might have played trick with his words when questions were raised against bitconnect.From my experience I have experienced that people managing communities can be really effective whether an ICO be a success or not.So I believe that bitconnect had a good community manager.And the most important point here is greed off course.People fall for false promises which promises them to make them rich overnight.
