Understanding Greenback Auctions
A greenback motion is an easy recreation, the place two members bid on a greenback invoice. The best bidder receives the invoice. Nevertheless, the loser should pay the quantity that they supplied as nicely. When bidding within the recreation begins to strategy or go past $1, the gamers’ recreation targets change.
