I hate this thread keeps coming up. A bitcoin union will not and can not ever work.
On this we would need a great deal of miners in same area and on same power company. This is not realistic for all miners to be on same. The data center's that use ton's of power.... tend to go to places with good deals on electricity. So the places where lots of usage is happening... they already have good rates.
I too, say a complete no to Union.
If something like 'United Miners of Bitcoin' exists, it may strike and force all exchanges to have higher prices or whatever, and it will even break the decentralization of bitcoin mining community.
It's not that I don't like the idea... if it was possible then I would think great. But even if all home/hobby miners made a pact... do you think the big operations would shutdown if price was not above X? No they are not going to. If we could control BTC price it ruins decentralization.
People keep bumping a topic that at it's core does not make sense. It is a free market on price of BTC. There is no big boss, no company to go up to with demands like a union would. It being impossible to achieve this is why I wish this thread would die or be locked. But it keeps going on... and on.
