Why are bitcoins being sold at 1/3 market value at bcchanger.com?
Are the lowball sellers trying to scam people or throw away money?
If you look at low price orders posting date, you will notice most of them are relatively older OR with zero feedback. The ones that with some positive feedbacks are genearlly in line with the price of the order posting date.
So it is more of a combination of old orders and scams.
