Let there be no doubt in anyone's mind that Swoggi is a barely "legitimate" SCAM. Let me define for you the term "scam". I consider a scam to be some system that draws funding from a customer base with very little, if any chance that it will deliver a return of product or value for the investment.
Swoggi takes your money without properly explaining the risks involved and how quickly your money disappear from Swoggi Credits (which are usable) to premium Credits which are not, unless you invest more money in the SCAM. Your chances of actually getting a good deal at an auction for anything worthwhile are tiny.
My recommendation, having lost a significant sum - DO NOT GO ANYWHERE NEAR SWOGGI!!
There is no such thing as a free lunch.
