I agree that we shouldn't buy these. But we need to buy something!
This was advertised as paying off the original investment in 3 months, and now it's more like 7.5. That's probably the reason share prices have stayed flat. With mining especially, time is crucial. Sitting on our investment rather than mining with it is not acceptable.
With increasing difficulty across the board, I'm not so sure the shares will ever pay off.
This is exactly how to fail.
In a competitive market like Bitcoin mining, the people that are in a hurry to invest are the people that lose the more money.
A return on investment in 7.5 months is wonderful. Most Bitcoin miners will never have any ROI.
Soon there will be new ASIC-scrypt, new ASIC-BTC and new GPUs with much better price, this is the law of the free market. When it happen, if you spent your money you'll not be able to buy, it will be too late.
The people that make money in mining are smart and patient.
