" Domains will faster increase in value than any other value mankind has ever known before" (Bill Gates)
This doesn't only sound great ! To buy domains with a target in mind and to trade them is a good business if one knows how to approach. In the perfect case a domain can be registered for a small amount of money only (e.g. some Euros) and then can be sold for six or even seven digit high prices.
Using this system high values can be generated fastly - assumed you choose the "right" domains.
