PLEASE STOP YOUR COIN2 DEPOSIT TO EXCHANGES !
WE HAVE A NETWORK SECURITY PROBLEM. The transactions are not confirmed anymore.
Wait for further instructions. HERE IS A WAY TO CANCEL YOUR UNCONFIRMED TRANSACTIONS AND TO RESTORE YOUR WALLET BALANCE:
For anyone wanting to reclaim "coins sent, but still with 0 confirmations", without re-downloading the blockchain...
This should recover unconfirmed sent coins back into the available balance (on windows)...
1. Open the C2.0 wallet.... Help > Debug Window > Console > 'repairwallet' >> Recovered amount will be displayed in output.
2. Close the C2.0 wallet...
3. Open the c2.0 wallet with "-rescan" parameter *
4. The recovered coins should now be included in the available balance.
* Shortcut Example
"C:\Coin2.0\coin2.0-qt.exe" -rescan
* CMD Example
cd c:\Coin2.0
coin2.0-qt.exe -rescan
Edit To Add:
As far as I know, this should work on any QT wallet.
Thank you FredDag, it worked fine for me and for others people.
