INTRODUCTION TO BITCOIN MINING
Some school of thought has it that bitcoin mining involves minting cryptocurrency and verifying or creating a new blockchain. We know that on average, every ten minutes a block is confirmed. This is one of the concepts that support the decentralization of Bitcoin or cryptocurrency in the world since no one has central authority to stop or influence the creation and verifying a blockchain.
Blockchain is a public ledger where all the transactions are recorded and on an average every ten minutes a new bitcoin block is mined which is then verified by the miners and the miners who has mined this block is rewarded with 6.25
BTC which are halfed at each having.No new blockchain is created in this process so you are wrong on this part.The decentralisation comes as no single miner have the full control of network and each transaction is verified and then included in the block with thousands of nodes across the network.
An average person can’t afford this.
With mining difficulty being increased and mining pools implementing heavy GPU in mining process it's nearly impossible for solo miners to mine bitcoin block but there are some
rare chances But you can join mining pool and use your hash power mining jointly with them and if you succeed you will get rewards according to it.
EFFECT OF AMOUNT OF ENERGY CONSUMED IN MINING BITCOIN
According to an article written by, Shawn Tully, 2021 states that “The report states that each Bitcoin transaction kilowatt-hours of electrcity. That’s the volume of energy that could “power the typical American home for six weeks,” the authors add. The Bitcoin mining that enables a purchase, sale, or transfer, it posits, uses a slug of electricity that costs $176. That number is based on an average worldwide cost per kWh of 9.0 cents over the past 12 months”.
There are many such articles and do you think they are solely right about it? They are published by the government media to defame the image of bitcoin and this electricity consumption has always been issue to them whereas the other banking sector consume way more energy then bitcoin but they only have problems with it.Moreover if you check miners are also using green energy and it's shifting to renewable energy sources but they will not show you truth and you have to check it for yourself.
EFFECTS OF MINING BITCOIN USING ELECTRICITY:
Radiation from those multiple mining systems emits a lot of radical rays which contain cancerous substances that can cause harm to society.
Could you please tell the source where you have find about this radiation concept related to bitcoin mining as there is no chemical experiment going in the factory so don't know where you have read about this.
And as suggested the more you research about bitcoin the more you will learn about it and having newbie view on anything is not good until you have deep research about it and if you want more information about mining then visit
