Well Bitconnect is certainly not a scam.
Lets put it this way... if you invest $19,000 for 1 btc today and hold it for 2 years, it might be worth $100,000.
If you invest the same amount of money, $19,000 in to bitconnects platform, in 2 years you would earn $230,000 a DAY with compound interest.
I have friends who have $100,000 loans on bitconnect and earning $1,000 a day.
Bitconnect is not a scam. One can invest $100 and see how well it does.
