About How Bitcoins Are Made
Let us say you had one legit $20 and one really good photocopy of that same $20. If someone were to try to spend both the true bill and the fake one, someone that took the problem of looking at either of the invoices' serial numbers would observe that they had been exactly the exact same number, and thus one of them needed to be fictitious.
This isn't a perfect analogy--we will explain in more detail below. .
Once a miner has confirmed 1 MB (megabyte) worth of Bitcoin transactions, they are eligible to win the 12.5 BTC. The 1 MB limit was set by Satoshi Nakamoto, and can be a matter of controversy, as some miners think the block size ought to be increased to accommodate more information.
Note that I stated that verifying 1 MB worth of transactions makes a miner qualified to earn Bitcoin--not everyone who verifies transactions will receive paid out.
1MB of transactions can technically be small as 1 transaction (though this is not at all common) or a few thousand. It depends on how much data the transactions consume.
In order to earn Bitcoin, you need to fulfill two conditions. One is a matter of effort, one is a matter of luck.
2) You must be the first miner to arrive at the perfect answer to a numeric problem. This process is also known as an evidence of work.
The good news: No advanced math or computation is involved. You may have heard that miners are solving difficult mathematical problems--that's not true at all. What they are actually doing is trying to be the first miner to come up with a 64-digit hexadecimal number (a"hash") that is less than or equivalent to the target hash.

The bad news: Because it's guesswork, you need a lot of computing power in order to get there first. To mine successfully, you need to get a high"hash rate," which is quantified in terms of megahashes per second (MH/s), gigahashes per second (GH/s), and terahashes per second (TH/s).
If you want to estimate how much Bitcoin you could mine with your mining rig's hash rate, the website Cryptocompare offers a helpful calculator.
Either a GPU (graphics processing unit) miner or an application-specific integrated circuit (ASIC) miner. These can run from $500 into the tens of thousands. Some miners--especially Ethereum miners--buy individual graphics cards (GPUs) as a low-cost method to cobble together mining operations. The photo go to website below is a makeshift, high-tech mining machine. The cards are those rectangular cubes with whirring circles. Note the sandwich twist-ties holding the pictures cards into the metal rod.
Example: I tell three friends I'm thinking of a number between 1 and 100, and that I write that number on a sheet of paper and seal it in an envelope. My friends don't have to guess the specific number, they just have to be the first person to guess any number that is less than or equal to this number I am thinking of.

Let's say I'm thinking about the number 19. If Friend A guesses 21, they lose because 21>19. If Friend B supposes 16 and Friend C guesses 12, then they've both theoretically arrived at viable answers, because 16<19 and 12<19. There is no"extra credit" for Friend B, even though B's answer was nearer to the goal answer of 19. .
In Bitcoin conditions, simultaneous answers occur frequently, but at the end of the day there can only be one winning answer. When multiple simultaneous answers are presented that are equivalent to or less than the target number, the Bitcoin network will decide by a simple majority--51%--that miner to honour. Normally, it's the miner that has done the work, i.e.

The number preceding has 64 digits. Easy enough to understand so far. As you likely noticed, that number consists not only of numbers, but also letters of the alphabet. Why is that
In order to understand what these letters are doing in the center of numbers, let's unpack the word"hexadecimal."
As you knowwe use the"decimal" go to the website system, which means it's base 10. This in turn means that each and every digit has 10 possibilities, 0-9.
