# Getting The Money To Bitcoin To Work

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 both of the invoices' consecutive numbers would observe that they were the same number, and consequently one of them had to be false.

That isn't a great analogy--we'll explain in more detail below. .

Once a miner has confirmed 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 can be 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 theoretically be as small as 1 transaction (although this is not in any way common) or several thousand. It depends on how much data the transactions take up.

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

2) You must be the first miner to reach the right answer to some numeric problem. This practice is also known as a proof of work.

The good news: No advanced math or computation is involved. You might have discovered that miners are solving difficult mathematical problems--that's not true at all. What they are 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: Since it is guesswork, you need a good deal of computing power in order to get there . To mine , you need to have a high"hash speed," that 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 just how much Bitcoin you could mine with your mining rig's hash pace, the website Cryptocompare provides 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 photograph below is a makeshift, home-made mining machine. The graphics cards are such rectangular cubes with whirring circles. Note the sandwich twist-ties holding the graphics cards into the metal pole.

Example: I tell three friends that 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. these details My friends don't have to guess the exact number, they just have to be the very first person to guess any number that's less than or equal to the number I'm thinking of.

Let's say I am thinking of the number 19. If Friend A guesses 21, they shed because 21>19. If Friend B supposes 16 and Friend C guesses 12, then they have both technically came at Related Site 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 goal answer of 19. .

In Bitcoin terms, simultaneous answers happen frequently, but at the end of the day there can only be one winning answer. When multiple simultaneous answers are presented which can be equal to or less than the target number, the Bitcoin network will decide by a simple majority--51 percent --that miner to honour. Normally, it is the miner who has done the most work, i.e.

## Unknown Facts About How To Make Money Through Blogging

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 these letters are doing in the middle of numbers, let us unpack the word"hexadecimal."

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