It’s a total scam
It’s a total scam! They pretend to be a very big company in Argentina and ask you to do a large translation. I worked on something full time for 7 days. I wrote an invoice and was asked to contact their cashier in the US. He asked me to open an online account at Equinox E-banking. I did so. They 'paid' my invoice, so I could see it in my 'bank account'. To be able to withdraw the money to my bank account in Denmark I needed to inform the bank about my banks BIC-code. Their system didn't recognize the code, and I was asked to pay them 500 USD (refundable) to open the channel between Equinox and my bank. I declined the request and subsequently discovered that my account at Equinox Bank was no longer accessible. The people behind all of this keep on contacting me though. The latest information was that they could lower the price for opening the channel to 200 USD.
They really are crooks. Stay away from them.
