dont forget that in 2016 btc income from mining will be half
but the value will be also very high, the current value already is about 100% more than what it was, so easily at this point will not count anything, incomparison when we were at 230
The price of bitcoin is not certain to rise. That is just a speculation. But the blockreward is going to halve, that is certain.
the point is that because of the certainty that the block reward will be halved, you have also somehow, the certainty the that price will increase
otherwise it's like saying that bitcoin is doomed to fail at some point
The only thing I am worried is I think some of the huge operations likely if cut in 1/2 still could operate in profit (like Bitfury if they have the gear we suspect). So there are likely some big guys with electricity so low they can keep going where normal electricity people will be left behind.
We have a while that I hope to see bitcoin slowly build up value. But if it does not I fear big players still can mine and little guys will be stopped.
ah eyah those with free electricity, might mine forever even if bitcoin is at zero
but people shoudl remember that those user are the minority, i would not believe ever that there are even 100 peta out there of "free electricity"
the whole network will not be able to survive only because there are a bunch of due with free electricity
