# Some Known Questions About Money To Bitcoin.

Let's 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 trouble of looking at either of the bills' consecutive numbers would see that they were the same number, and thus one of them needed to be fictitious.

This isn't a great analogy--we'll 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 established by Satoshi Nakamoto, and is an issue of controversy, as some miners think the block size should be increased to accommodate more information.

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 technically be little as 1 transaction (though this is not at all 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 issue. This practice 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 is not true at all. What they are actually 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 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 , you need to have a high"hash speed," 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 along with your mining rig's hash pace, the site Cryptocompare provides a helpful calculator.

Either a GPU (graphics processing look at here unit) miner or an application-specific integrated circuit (ASIC) miner. These can run from \$500 to 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 below is a makeshift, high-tech mining machine.  The graphics cards are such rectangular cubes with whirring circles.  Note the sandwich twist-ties holding the pictures cards into 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 need to guess the specific number, they simply must be the very first person to figure any number that's less than or equal to the number I'm 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 have 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 look at these guys 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%--which miner helpful hints to honour. Normally, it is the miner that has done the most work, i.e.

The losing block then becomes an"orphan block" .

Now imagine I present the"figure what number I am thinking of" question, but I'm not asking just three friends, and I am not thinking of a number between 1 and 100. Instead, I'm 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 hard to guess the right answer.

## The Buzz on Bitcoin Mining Code

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 center of numbers, let us unpack the word"hexadecimal."

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