about ecology affect:
You all say btc is a very small part of world energy system, u say that asics and infrastructure linked with it are take a very small affect on world.
By you forget about localization factor.
What if we take all of mining stuff in the world and place it in one city. You will not be able to breathe in that city I think.
oh of course one city is a tiny part of world, isn't it?
Ghash.io is just one warehouse. google has more servers then ghash.io.. its just the hashing power of ghash.io is more because the computing unit is a asic chip not a cpu/gpu that google has..
people need to realise that a box smaller then a show box has more hashing power then two 7 foot tall server racks. so google has more computer units but wont match ghash.io's speed of mining due to the technology difference.
so take palo alto. there are more physical computer unit combined in that one city than bitcoin miners. so if we swapped out the computers and servers and made palo alto into a bitcoin mining farm city palo alto's electric will go DOWN
