I just clicked on a transaction on the left tabs and i found the coins i earned today. It has a question mark. When i hover over it it says 'generated but not worked out'.
Do i have to wait or do i have to do something.

Guys I'm new to crypto
After reading your first post, it is possible that your wallet staked on the wrong chain.
Go to the help menu > Debug window, select the Console tab and type the command: repairwallet [enter]
An other possibility is to enforce a rescan using the -rescan argument while the wallet is starting. It will rescan all your transactions in the local database.
To make the rescan:
1. Close your wallet
2. Create a shortcut to the b3coin-qt.exe on your desktop or elsewhere.
3. Right click on the shortcut and select Properties
4. Add the -rescan argument on this model (don't modify the path) "C:\Program Files (x86)\B3Coin\b3coin-qt.exe" -rescan
5. Click OK and start your wallet using the shortcut.
6. Check your transactions again
7. Delete the shortcut
Your wallet should stake again on the right chain.
You can send me a PM to confirm if it worked or not.
