When "blocks" of verified transactions are completed and added to the blockchain, bitcoin miners are rewarded with bitcoin. But, why does Bitcoin need BTC miners? Let's see.
Why Bitcoin Needs BTC Miners
The computational work that nodes in the network undertake in the hopes of earning new tokens is referred to as "mining" on the blockchain. Actually, miners are essentially being rewarded for working as auditors. They are responsible for verifying the legitimacy of Bitcoin transactions. Satoshi Nakamoto, the person who created Bitcoin, came up with this standard with the intention of keeping users honest. The "double-spending problem" is prevented by miners by verifying transactions.
Double spending is a scenario in which a Bitcoin owner illicitly spends the same bitcoin twice. This isn't a problem with physical currency, though. For example, if you hand someone a $20 bill to buy a bottle of vodka, you no longer have that $20 bill, so there's no chance you could use it to buy lottery tickets down the street. Despite the possibility of counterfeit currency, it is not the same as really spending the same dollar again. However, there is a possibility that the user could Duplicate the digital token and send it to a business or other entity while keeping the original with digital cash.
Imagine that you have a real $20 bill and a $20 counterfeit bill. If you were to try to spend both the real bill and the fake one, someone who took the trouble of looking at both of the bills' serial numbers would see that they were the same number, and thus one of them had to be false. Similar work is done by blockchain miners, who verify transactions to ensure users didn't attempt to spend the same bitcoin twice inadvertently.
How Much a Miner Earns
Every four years or so, the Bitcoin mining earnings are cut in half. You could earn 50 BTC for mining one block when bitcoin was originally created in 2009. This was cut in half to 25 BTC in 2012. This was cut in half again to 12.5 BTC by 2016. The payout was once more cut in half on May 11, 2020, to 6.25 BTC.
With a price of about $39,000 per bitcoin as of March 2022, you would have made $243,750 (6.25 x $39,000) for finishing a block.
