This is really your fault. Btce has been always a shady exchange. A catastrophe in the making. I do use it because they offer lots of USD withdrawal options and are lax with the rules but if I was selling to hedge my bitcoin value and I don't want to go with the identity verification I'll use bitfinex/kraken/bitmex. The latter is not an exchange but recently their quarterly future is solid enough for 20-40k.
That's only about 40 BTC so I very much doubt they would decide to exit based on that amount...
