Thank you for all the responses. I tried the customers service on the site, but didn't get any respons.
I started using this site back in 2013, back than it didn't have any problems. But I didn't spend a lot of money on it.
I was planning to send my bitcoins to a more reliable wallet. But the minimun amount for sending was higher than my credit. So to up my credit, i send the 50$.
Hopefully I somehow get my bitcoins, but I don't have a lot of hope.
I also used Vircurex back in 2013. They were an up-and-coming altcoin exchange at the time. Unfortunately, they suffered a hack years ago, and were never able to recover. They froze user balances pro rata based on the amount of coins hacked, with the intention of gradually "unfreezing" balances as trading commissions came in. Rather, volume dried up on the exchange and traders exited with whatever they could. I'm frankly surprised that the site is still up and running right now.
Anyway, I'm not confident you will see your coins. New deposits (post-hack) were never supposed to be added to "frozen" balances, but at this point, I'm not sure that Vircurex intends to act honorably. But you should probably keep trying to contact support. It's possible they will still credit the coins and that their node is just offline.
Keep us updated.
