Sell mine too.
Now a legitimate and transparent business would provide the names of the bidders and the actual bids.
At least tell us 3 of the 8 bidders and the mean, median, and mode of all 8 bids.
The "mode" (most frequently occurring bid) is important because if you were to know that 7 of the 8 bids were at 0.0000001% then this is effectively a bid of zero, and there really would be only 1 bid that Prosper obtained and not 8.
I'd still want my loans sold at the bid price, but it would be harder for Prosper to continue perpetrating this charade on lenders.
Prosper, just be honest and forthcoming--all the kickbacks and backroom dealings always come out in the end. Sure, you can hide for a while but eventually it all sees the light of day.
