Miners who 'dig' for Bitcoins use enormous amounts of electricity just to be able to mine few satoshis. Well, some claim (mostly governments) that it distributes negative impact to environment.
Electricity Concerns
Too much electricity produced and consumed by mining cryptocurrencies will in turn create huge volume of greenhouse gases.
Technically, it takes 10 minutes to mine one bitcoin. It will take 72 Terawatts of power to mine a bitcoin using the average power usage provided by ASIC miners.
Crypto mining using your own hardware sounds very expensive, including all the electricity cost and the legality will really matter in your country. Bitcoin are now illegal in China, Pakistan and a number of countries.
List of Countries where Mining is Illegal
These countries ban Bitcoin mining because of environmental concerns. I CALL THIS B.S. by the way.
Another Alternative
I have recently came across for an alternative to mine Bitcoin without having to setup the complicated hardware.
I am using CryptoTab. It's the world's very first internet browser which has a mining feature. CryptoTab Browser, with its mining algorithm allows using your computer resources more effectively than in extension format.
This new browser boosts mining speed up to 8 times, which in return increases Bitcoin earnings.
CRYPTOTAB Features
CryptoTab must be used regularly for browsing websites, researching, for social networking, watching online videos, and all your online activities. Use the CryptoTab browser as your default one everyday to gain much advantage.
I'm now using this for only a day already and look at how much my Bitcoin mining is progressing.
You can give this a try anytime now.
Cheers!
