The current status of AM is debatable. But I think we can all agree you bought at the worst possible time. 4btc/piece would require like 40% network hashrate which will probably never happen.
Assuming zero profits from sales. It reached 4+ on the back of sales. Granted, that window is only open by a crack compared to last summer, but still counts for something. 4+ is a dream, perhaps, but 10% network + some sales shouldn't be unmanageable. Another point would be newer investors, happy with less than 33% APR - that could raise the price as well.
