algo_trader I have the same situation, and in my case it is 0.795 BTC

@LiveCoin I see that my BTC were moved from my old deposit address:
https://blockchain.info/address/19amgw2DUsJohFw3kJABeGmV3dBP7kGAuS
at 2018-03-19 14:50:06

and they were moved to Livecoin main wallet, just like all previous deposits:
1GTDsES25s4HsN7jws9irPXMaqzjQB7W7q


can you tell me who and how done it?

when I made ticket regarding my problem I got reply:
"The old node is completely deleted, it is impossible to process transactions to the old addresses."

so it looks like it was a lie...
