"hundreds of thousands to millions of dollars." is quite a large range when talking about money.

My comment was specific to the example given in the article, where to amount was about $195,000. While not a tiny sum of money, the amount of man hours spent to unravel those transactions, to ultimately get to recoverable sum, would be close to if not more than the original amount. And getting to the amount, may not guarantee that you can recover the funds anyway.
