by the time you get your machine, their bitcoins double in price, they make profits.
You can only say this for fact in hindsight. at 1000/btc it's hard to imagine it doubling by March.
I don't like long term predictions for bitcoin but do you believe that anyone was thinking that bitcoin will go from 200$ to 1200$ in one month? Absolutely noone. Even the more bullish among the bulls couldn't have thought of such a rise.
True. But then there is a day like today where BTC drops 30%! Glad I physically couldn't get my money in early this week. Hopefully by next week my LTC miners should be here if people don't stop buying the damn video cards
Bitcoin dropped 50% or even more actually but what can you do when you have officials like the bank of china saying that bitcoin should not be used as a currency. (Whatever that means anyway)
