I put a couple of friends onto Ivykoin who have made about $5m over the last 18months(the are poker players)and when discovery came back to them from WA they wanted a pdf filling in with all personal details and was mentioned about TAX obligations.....
As soon as they read TAX they deleted the email LOL......
They have their money all untraceable(so they think) and they dont want to start poking the stick in the face of the tax man if the can help it, no matter how good the coin looks....
