Ross Asset Management was the biggest Ponzi-scheme ever happened in NZ when it unfolded in 2012 – it is said investors had $450 million with Ross but only $10m was recovered. In reality the figure invested was closer to $110m as most of the $450m were accumulated fictious returns. About 200 have signed up to the claim so far.
You've probably heard the saying "If it sounds too good to be true, it probably is." This rings particularly true in the case on Ponzi schemes.
A Ponzi scheme is not a new wonder drug or an Italian beach resort, it's terrible for your financial health.
