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 is still a lot of debate, on the one hand, mining bitcoin is something we can say "damaging" the environment because of inefficient use of energy, while on the other hand many blockchain projects in the name of green energy, but many have not been realized
