Holds: money behind every bid
Online, talk is free. Anyone can comment “I’ll take it”, negotiate for a week and disappear. In an auction a fake bid is worse: it pushes the price for everyone.
So on HyperBidz, the top bidder always has 2.5% of their bid held from their wallet. Get outbid and the hold is released that same moment. Only one person, the current leader, ever has money held on a lot.
When the clock hits zero, the winner’s hold becomes the fee. That’s why the price you see is real: the person behind it has already committed.
