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 has been attacked for most part of 2018 and this has really impacted on the market price and value of bitcoin and all these attacks are coming from government on the ground that bitcoin is anonymous and could easily be used for crimes and drugs. If another attack that will be coming from the environmental angle hit bitcoin then there will be much problem for the coins to make it. I will like to suggest that miners should consider another source of energy that is environment friendly like solar, wind and hydropower for energy source. This will go along way to shift attention from bitcoin.
