IMHO I think bitconnect falling and BTC falling around the same time are related there was so much money being thrown into bitconnect via btc and after all these people lost a bunch of their money the entire crypto market started falling but that is just my opinion what do i really know :O
BUt other than that bitconnect was bought because of potential profit, hek I knew 100% it was a scam but figured other people that knew it was a scam though "ehhh I can get in and get out" and some did some were smart/lucky enough to get out at the perfect time

Others not so lucky and then we see btc drop to almost the price it is now in a very short time period....
