can someone maybe help me. I just opened my wallet today after I exported it to a private key and incrypted it (Multibit wallet) and more than half of my coins has been send out to an address I dnt know. According to what I can see in the transaction History of this transfer it has been used as transaction fees for someone els`s transfer of coins. Can this be a problem on the blockchain side or was my wallet hacked. Any help will be greatly appreciated.
