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?
I do not think people know it is a fraudulent coin. Investors who pour money into Bitcoin are not knowledgeable about Crypto. They are just greedy people and want fast money. Some people have been cheated because of lack of knowledge. I think that's the main reason.
