You've enough answers from the people here and I'll add to that and confirm that they are right with Bitconnect. It's just a ponzi scam that let their investors think that they are actually investing to a coin and has some magical bots but that's not literally what they want to happen and they are only tricking investors.
I almost believe, many people share it on facebook. if about money everyone will be interested.
Those people doesn't know how to exit now as they have to get more referrals but too bad they didn't knew that it's a ponzi even before. Get away from bitconnect and don't waste your money there.
