How Money To Bitcoin can Save You Time, Stress, and Money.
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 imitation one, someone that took the problem of looking at both of the invoices' consecutive numbers would observe that they were the exact same number, and consequently one of them needed to be false.
That isn't a perfect analogy--we will explain in more detail below. .
Once a miner has verified 1 MB (megabyte) worthiness of Bitcoin transactions, they are eligible to win the 12.5 BTC. The 1 MB limit was established by Satoshi Nakamoto, and is a matter of controversy, as some miners think the block size ought to be increased to accommodate more information.
Note that I said that verifying 1 MB value of transactions makes a miner eligible to earn Bitcoin--not everyone who supports transactions will get paid off.
1MB of transactions can theoretically be as little as 1 transaction (though this is not in any way common) or several thousand. It depends on how much information the transactions take up.
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 right answer to a numeric problem. This practice is also known as a proof of work.
The good news: No advanced math or computation is involved. You may have discovered that miners are solving difficult mathematical problems--that's not true in any way. What they are actually doing is trying to be the first miner to think of a 64-digit hexadecimal number (a"hash") which is less than or equal to the hash.

The bad news: Since it is guesswork, you need a good deal of computing power in order to get there first. To mine successfully, you need to have a high"hash speed," that is measured in terms of megahashes per second (MH/s), gigahashes per second (GH/s), and terahashes per second (TH/s).
If you want to see post estimate just how much Bitcoin you could mine along with your mining rig's hash pace, the site Cryptocompare offers a helpful calculator.
Either way a GPU (graphics processing unit) miner or an application-specific integrated circuit (ASIC) miner. These can run from $500 to the tens of thousands. Some miners--particularly Ethereum miners--buy individual graphics cards check this site out (GPUs) as a low-cost way to cobble together mining operations. The photo below is a makeshift, high-tech mining machine. The graphics cards are those rectangular cubes with whirring circles. Note the sandwich twist-ties holding the graphics cards to the metal rod.
Example: I tell three friends that I'm thinking about 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 need to guess the exact number, they simply have to be the first person to guess any number that's less than or equal to this number I'm thinking of.

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

The number preceding has 64 digits. Easy enough to understand up to now. As you probably noticed, that number consists not just of numbers, but also letters of this alphabet. Why is that
In order to understand what these letters are doing in the center of numbers, let's unpack the term"hexadecimal."
As you know, we use the"decimal" system, which means it is base 10. This in turn means that every digit has 10 chances, 0-9.
