There are some news about hacking my account. There is charts bitcoinwisdom.com/markets/btce/ltccnh here.
if you go on the chart to 07/02/2015 3-30AM you will see the price down to 1 CNH for LTC on the candle. That was the time when my account was hacked and all deals from my account were made 3-30 - 4-00 AM.
But if you go on the chart to 07/02/2015 1-30 AM you will see the similar price down to 1 CNH for LTC on the candle with an even bigger volume sold.
Therefore I can make a definite conclusion that there were some other people who suffered from that hack (I really doubt that somebody would have made deals on LTC/CNH by that price on his own money)
That means that either the btc-e was hacked through there own vulnerability or there was thief inside btc-e team.
