"Think of it this way. When bitcoin first launched it had NO value at all, so it wasn't profitable to mine then and costed far more in electricity, but look where we are today."
That is a very good point.
Manufacturers ASICs hardware constantly rising bitcoin price,with relatively little money.
but it will not be much longer ,
max 4-6 next month, and after that bitcoin is dead.
The clear evidence for this is mining factor.
The minimum is 25 cents per GHash at 24h,
When it approaches the border 25 cents per Gh, Bitcoin price hard rising and make corection mining factor, above 25 cents per 1GHash at 24h.
The next difficulty rise is for about 7 days 20%, or BTC price go to 1300 USD, (each 10 days rising 20-25%)
Where is the end ? In april-2014 year we'll have the price 10 000 USD
