In my opinion they could be running a very sophisticated scam on top of a crypto. There are elements of a pyramid scheme along with some other red flags that people have pointed out. You have to "lock up" your funds for 299 days if its less than $1000. Additionally you have to buy in with BTC and then trade it for their BCC (Bitconnect Coin) which raises the price. Then you trade that coin to their "trading bot" which gives back variable interest rates daily. Their coin has gone up to $65 now from $10 in less than 4 months but they only pay out in USD not in their coin which is now gone up in value (and you happened to trade them).
