No the tokens aren't lost yet as it was a legit address. The coins which are sent to wrong addresses will be lost in a limbo.
In your case the wallet address was right but non functional. In this case you must contact the Hitbtc support and tell them your querie.
Althouh your funds are at a risk, the Hitbtc support might help you. This is why you must always check the wallet status before depositing any amount in it.
Its been 4 days now no response from HitBTC support. :/
They could help you. If you meet
these conditions, you should contact them otherwise your coins are lost sadly.
Yes i read that before and unfortunately my tokens don't worth $100 and that article says "$100 is being deducted from the amount of that deposit."
