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?
Bitcoin is very sustainable and now the very successful crypto currency all over the world and we all know that this is human psychology that in every success there are some people who are being jealous of that success every time and the same thing is happening with bitcoin also there are rumours that in the coming decade it will be using twice the amount of electricity as use by the entire world currently, though the bitcoin mining requires some amount of electricity but this doubling the amount of electricity use of the entire world is completely hypothetical in my opinion.
