Dear Clients,
Effective immediately World Bitcoin Exchange (WBX) will be shutting down trading / deposits and returning all client funds.
Due to increasing fraudulent transactions on our accounts, WBX can not operate in it's current capacity. Combined with multiple bank account closures, we have deemed the best course of action is to halt trading.
Sincerely,
Andre Jensen
No timeframe is given, and there are no updates on the WBX site.
