There have been rumors going around that Mint is going to be pumped, and the rumors could be possibly true, but there is a 96893107.37617337 sell wall set at 24 sat on Mintpal. So unless this order is set by the pumpers to keep prices low until the pump is ready, it will be difficult to break through the wall. But it is clear Mint prices are being kept artificially low.
Didnt you see the 25 bitcoin buy in one hit about an hour on cryptsy at 25 satoshis?
These are simply cappers trying to get more cheap.
