Thanks for some reassurance.

Situation looks a bit worse now - first of all transaction is still "pending", not even registered in blockchain (can't find it on etherscan).

Secondly, I found that they had some hacker activity 2nd of December on one of smaller markets. More info in their announcement https://blog.hitbtc.com/official-statement-on-amm-micromoney-token-markets-issue/

I hope they suspend withdrawals only until they resolve the case.

Can I ask You when did You do Your LTC transactions?

[edit] - whoah transaction appeared in etherscan. That's a big step forward.
