Today I read this article.....
https://www.ccn.com/bitcoins-electricity-usage-could-power-all-of-austria-in-the-future/It says in 2018 Bitcoin mining may consume 0.5% of worlds electricity in 2018.
I think this is because the mechanism "PoW" of Bitcoin. It costs a lot of power. And it looks like this statistics only includes Bitcoin, but there are still other coins can be mined.
I am sure for some people this is not environment-friendly and this could be used as the reason to restrict Bitcoin.
Will this affect the future of Bitcoin? or will there be any new energy-saving mining method for Bitcoin or other coins? How do you think about this?
There was a rumour all around the world that the electricity consumption of bitcoin is very high and in the coming decade bitcoin will going to use double the amount of electricity as used by the entire world currently so I think this is a work of FUDs and they are trying to bring down the valuation of bitcoin and this is all rubbish because now everyone knows that bitcoin is very sustainable crypto currency and there are millions of people around the world who are investing in bitcoin and they are satisfied with the bitcoin services.
