so whats my next step? AFP, ACCC? I'm owed over $1600.

Seems like these guys have run off with the money. I always knew bitcoin was a high risk venture, and I only put in what I could afford to lose, but it's never nice to be caught out by scammers who looked pretty legit to me.

This is why bitcoin will never get off the ground in any meaningful way, there just isn't any reasonable recourse to be had
