# Rumored Buzz on Bitcoin Trading History

Let's say you had one legit $20 and one really good photocopy of that same $20. If someone were to attempt to spend both the true bill and the fake one, someone who took the trouble of looking at either of those bills' serial numbers would see that they had been exactly the same number, and consequently one of them had to be fictitious.

This isn't a perfect analogy--we'll explain in more detail below. .

Once a miner has verified 1 MB (megabyte) worthiness of Bitcoin transactions, they are entitled to win the 12.5 BTC. The 1 MB limit was set by Satoshi Nakamoto, and is an issue of controversy, as some miners think the block size ought to be increased to accommodate more data.

Note that I said that verifying 1 MB value of transactions makes a miner qualified to earn Bitcoin--not everyone who supports transactions will get paid off.

1MB of transactions can technically be little as 1 transaction (although this is not at all common) or several thousand. It depends on how much information the transactions consume.

In order to earn Bitcoin, you need to meet two conditions. One is a matter of effort, one is a matter of luck.

2) You have to be the first miner to reach the right answer to a numeric issue. This process is also known as an evidence of work.

The good news: No advanced math or computation is involved. You may have discovered that miners are solving challenging mathematical problems--that's not true at all. What they're doing is trying to be the first miner to think of a 64-digit hexadecimal number (a"hash") that is less than or equivalent to the hash.

The bad news: Because it is guesswork, you need a lot of computing power in order to get there . To mine , you need to have a high"hash rate," that is measured in terms of find here 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 can mine with your mining rig's hash rate, the site Cryptocompare offers a very 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--particularly Ethereum miners--buy individual graphics cards (GPUs) as a cheap way to cobble together mining operations. The photograph below is a makeshift, high-tech mining machine. The cards are such rectangular blocks with whirring circles. Note the sandwich twist-ties holding the pictures cards to the metal rod.

Case in point : I tell three friends I'm thinking about a number between 1 and 100, and I write that number on a piece 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 figure any number that's less than or equal to the number I am thinking of.

Let's say I am thinking about the number 19. If Friend A guesses 21, they shed because 21>19. If Friend B supposes 16 and Friend C supposes 12, then they have both technically came 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 target 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%--which miner to honour. Typically, it's the miner who has done the work, i.e.

The losing block then becomes an"orphan block." .

Now imagine I pose the"figure what number I am thinking of" question, but I'm not asking only 3 friends, and I am not thinking of a number between 1 and 100. Instead, I am asking millions of would-be miners and I'm thinking about a 64-digit hexadecimal number. Now you see that it is going to be extremely difficult to guess the ideal answer.

## The Bitcoin Mining Code Statements

The number above 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 middle of numbers, let us unpack the term"hexadecimal."

As you know, we use the"decimal" system, which means it's base 10. This in turn means that each and every digit has 10 chances, 0-9.
