Yes, you can still stake BCC coins. In fact, the network weight is really increasing so a lot of people are staking at the moment. I think people realize that BCC coins can be rebranded and used for something else in the future. It has a worldwide following and interest. Bitconnect would have kept going if not for all the jealousy, DDoS attacks and bankster/govt attacks on it. The establishment just does not want the little guy to stop being a wage slave, so they can keep a stranglehold on them.
