If you think about it, right in the middle of their name is the word "con" :-D
Honestly I have no issues with Bitconnect even though I was super skeptical at first. I have actually made about $860 back from a $450 investment without any referrals. The way that their system works is that Bitcoin AND their token keep going up in price over time so any "loans" given to them will be worth MUCH more by the time they have to pay out.
For example I bought something like 7.14 Bitconnect tokens at $63 each and spent over 0.18 BTC. That same amount of BCC tokens would now be worth $2364 and the BTC would be worth $2082... So you can see if they had held even HALF of the crypto I sent over they still have plenty of room for profit.
