My coins are not staking in wallet and it says: "Not staking because you don't have mature coins"
What does it mean?
My coins have been staking without problems so far, although I've just received 1 transaction in the past. Today after I received my 2 mined transaction the coins are not staking anymore.
The 2nd mined transaction is saying "Immature, 20 conformations will be available after 90 mined"
It means wait until they become mature again. After 90 confirmation it will mature and will start staking again.
