Time for the world's nations to come together and ban Bitcoin forever.

Time for the globalization of information to be accepted by the world's nations and to stop war on citizens representing potential science, but ultimately unavoidable libertarianism.

If only block chains mapped to something useful, two birds with one stone, or could be used in conjecture with distributed computing to compute something useful (meteorite tracking (perhaps the REAL common enemy of the World's Nations), (protein unfolding), ect.) Or had some kind of associative reward system, as the marginal benefit of coin harvesting falls.

If the crypto-underground were better organized(potential paradox as its power lies in being distributed) and did not copy the greed of their predecessors, they could have silence on the wire, in regards to warfare. And the future of computation, non-local.

Information is the modern commodity. What, if there is, use, the social construct decides.

I wonder if the same analysis of how much does it cost for the current financial system to do its business.

Heck why not ask how much of the worlds energy goes towards war.

If you really want to know one of the most important things that is missing in this world, accountability (honesty). Now if someone could just come up with a technology or ensure accountability.... hmmm, oh wait, there is such a technology. And what is this magical unicorn tech your talking about... its called "decentralized blockchain" aka cryptocurrencies.

How much does honesty already cost us... lawyers, judges, police officers, anyone with signing authority over anything else... and let's not forget the cost of all those people involved driving to work, the electricity those buildings use, the cost ... You know considering the above cost of current honesty what do we have, a massively corrupt system that is still trying to be justified as legitimate.

"the minimum current usage of the Bitcoin network at 2.55 gigawatts"

Don't you hate it when units get mixed up! The watt is a unit of power not current!

I agree with dbastianello. Bitcoin is the world's insurance policy against corrupted bankers and authorities. The small percentage of the world's energy use is probably worth it. Otherwise Bitcoin would disappear.
