Buying a wonderful asset on PIPA and facing financial setbacks shortly afterwards. That can be a reason to eventually cancel the purchase. And unfortunately PIPA's trust towards buyers is sometimes betrayed, especially by bidders who may overplay their hand and then don’t pay when their purchase has to be settled. Pigeons that don’t change owner as a result are offered again in this "non-payer auction". Pigeons of very different backgrounds, but real diamonds of golden lines often shine in the auction - as you are used to from PIPA.
