I start the mining I got the coins but I cannot spend it, do anyone has a solution to it
It needs to have at least 100 confirmations to be spendable.
In other words, you need to mine another 100 blocks.
I have mined 1000 blocks but still cannot spend it. I enabled the advanced wallet input control feature from the QT wallet and tried selective input to do a transaction but it is unconfirmed. There are 100 new blocks mined and still going on
