Something seems odd with all those names as many of them (perhaps the majority) seem to me at least to be basically worthless and even a reg fee a dubious value.
Can someone here explain why the bids are so high
P.S. I said that, without checking Suggestion Tool, or for links, for other extensions, google popularity, traffic, or existing websites for the name or similar names, so I may be wrong, just a quick non-researched judgement.
