Is bitconnect staking a scam or fake?

I have matured coins in my wallet for 3 days now. Since then it says "Staking." but nothing happens.

3 days ago it said: "Expected time to earn reward 1 day."
2 days ago it said: "Expected time to earn reward 12 hours."
1 day ago it said: "Expected time to earn reward 17 hours."
Today it says: "Expected time to earn reward 9 hours."

No stake has been credited so far. Wallet is up-to-date.

Can someone explain this?
