How smart you are?

While watching closely Hive-engine market, I have noticed an interesting behavior of certain bidders.

While to reach the main goal, and stay on top of buyer's list, it is enough to have your bid just a tiny fraction of % above all the other bids,
some people are so desperate, that voluntary are going to pay +26.6% (and often more) than is absolutely necessary

Are you doing the same?
I wonder - why?
