A Complete Sham.
You are bidding against a bot in place by the bank. Case in point; a recent property just 2 doors down from where I live went up for bid. I put in one bid with room for me to clean up the house and still make a profit. Only to watch the biding continue well past profitability for TWO HOURS at $250 increments. Is any real purchaser willing to waste two hours of their time placing $250 bids? Another tell is that they can reduce the bid increment and place a bid in the same instant. In the bid I mentioned, I watched the clock and the bid increment, the site shows a $5,000 increment at 3 seconds left, then the bid jumps by $2,500 and the increment drops to $2,500 resetting the clock. You never see the increment drop without a matching bid increase. Bottom line don't be fooled into thinking this site has any legitimacy!
