They closed the lending platform. Any active investment you had, they converted the USD value to Bitconnect Coins at a value of like $364/Per BCC... which is retarded because now the coin is essentially useless. That being said the BCC blockchain still works, you can stake coins or sell them on the exchange, however I think the coins are only worth about $18ish per coin on HitBTC, I haven't checked BCC's internal exchange.
TL;DR They gave everyone worthless BCC tokens that lost like 95% of its value. Sliver of hope that they try to do something with it in the future, fat chance imo though. I think they are gonna go away soon.
