Do not use Vircurex, they wil freeze your funds to pay off their own debts...
I 2nd this, I've heard horror stories about Vircurex.
They got hacked and was paying back some guy .00003 bitcoin a day(He lost 12 bitcoin), it would take him over 100 years to recieve his full amount of bitcoin again with the rate Vircurex was paying him back at..That exchange must be horrible.
