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?
This has been handled many times in this forum. And it is always exaggerated, whether it is for what purpose, which surely drops the image of Bitcoin. If it's true that mining consumes a large amount of electricity to exploit Bitcoin, of course the government will offer a more reasonable price to minimize this. So you don't have to worry too much about that.
