Last week (16FEB) I send 0.7 QRK to my Android Wallet.
When I look to the block explorer it indicates the following:
Send 999.9 QRK
When I click on the 999.9 QRK, it indicates that 0.7 QRK is send to my android wallet and 999.2 QRK to the following address: Qf5NfxzS4e7ymMMtw9BDNp85PUKro84yHX
That address is unknown for me.
According to the block explorer there is 999.2 QRK less in my wallet, than according to the paper wallet.
When I check the balance of Qf5NfxzS4e7ymMMtw9BDNp85PUKro84yHX this is 999.2 QRK.
What happened and can this be explained?
It sounds like you accidentally set up a transaction fee on your desktop wallet. It's also possible that you downloaded something and someone is trying to steal your Quarks.
