It screams HYIP Ponzi scheme, and many people are getting sucked into this trap. I have even seen comments of people selling off their cars/houses to invest in this.
Basically for those of you who don't know what it is, you lend Bitconnect money, they lock it up for a set time, and promise about 1% returns a day, up to 40% a month. To get a sense of how much that is: Charles Ponzi, the man that "ponzi scheme" originates from, promised 50% in 3 months.
Stay clear.
