Some people say BitConnect is a scam some say it is legitimate, what do you think? I've read many articles about it and I still not understand how it actually works.
It's definitely not legit. Anyone trying to convince you that Bitconnect is legit is trying to earn from you a portion of your investment because there are lucrative rewards involved with introducing new investors into this ponzi scheme.
And that's exactly what it is - a ponzi scheme.
If you don't understand how it actually works, it's probably fair to say that it is going to scam you. There is no way that the profits are going to keep rolling in.
