As far as what I can see is that you do not have a problem - it is change sent back to the mining pool that you use - just follow the audit trail. The received amount on the address is not the final balance of the address that belong to you. The total amount that the address received was 1,911.91034194 DTC and 314.90616155 DTC was returned as change with the final balance of the address being 1,597.00418039 DTC - just follow the transaction hash (40eed....) to see how much DTC was paid to many addresses from the mining pool and what change was returned to the mining pool.

This is  most likely one of the reasons why you should not mine directly to any online wallet or exchange address - rather set a limit on your mining pool and then request a payout to your address so that the coins that you receive are not newly generated coins.

Anyone else that can explain this better - please do so.

Tnx
