# The 8-Minute Rule for Bitcoin Trading History

Let's say you had one legit $20 and one quite good photocopy of the same $20. If someone were to attempt to spend both the real bill and the imitation one, someone that took the problem of looking at both of the invoices' 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 great 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 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 worth of transactions makes a miner eligible to earn Bitcoin--not everyone who verifies transactions will receive paid out.

1MB of transactions can theoretically be as little as 1 transaction (although this is not at all common) or a few 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 might have discovered that miners are solving challenging mathematical problems--that is not true at all. What they're actually doing is trying to be the first miner to come up with a 64-digit hexadecimal number (a"hash") which is less than or equivalent to the target hash.

The bad news: Since it's guesswork, you need a good deal of computing power in order to get there first. To mine successfully, you need to get a high"hash rate," which 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 estimate just 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 you could check here run from $500 into the tens of thousands. Some miners--especially Ethereum miners--buy individual graphics cards (GPUs) as a cheap way to cobble together mining operations. The photo below is a makeshift, home-made mining machine. The graphics cards are such rectangular blocks with whirring circles. Note the sandwich twist-ties holding the pictures cards to the metal pole.

Case in point I tell three friends that 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 exact number, they just have to be the very first person to figure any number that is less than or equal to the number I am thinking of.

Let us say I'm thinking about the number 19. If Friend A guesses 21they lose because 21>19. If Friend B supposes 16 and Friend C guesses 12, then they have both theoretically arrived at workable answers, because 16<19 and 12<19. There is no"extra credit" for Friend B, even though B's answer was closer to the target find out answer of 19. .

In Bitcoin conditions, simultaneous answers occur frequently, but in the end of the day there can only be one winning answer. When multiple simultaneous answers are presented that are equal to or less than the target number, the Bitcoin network will determine by a simple majority--51%--which miner to honour. Normally, it's the miner that has done the work, i.e.

## What Does Bitcoin Mining Code Do?

The number above 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 the alphabet. Why is that

In order to understand what Our site these letters are doing in the middle of numbers, let's unpack the term"hexadecimal."

As you knowwe use the"decimal" system, which means it is base 10. This in turn means that every digit has 10 possibilities, 0-9.
