Haas offers an API to Virtex however that exchange does not offer withdrawals or support of any kind. haas should not offer access to such a scam site that steals bitcoins. Haas is endorsing it by even offering a connection to it. Has anyone else had trouble Virtex?
Whats the problem with virtex? I have personally used it for testing when we first supported them, perhaps you can send us a link and we can check in with them about any possible issues?
