# Some Ideas on Money To Bitcoin You Should Know

Let us say you had one legit $20 and one really good photocopy of the same $20. If someone were to attempt to spend both the true bill and the imitation one, someone that took the problem of looking at both of those invoices' consecutive numbers would observe that they were exactly the same number, and consequently one of them needed to be fictitious.

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

Once a miner has confirmed 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 worth of transactions makes a miner eligible to earn Bitcoin--not everyone who verifies transactions will get paid out.

1MB of transactions can theoretically be as small 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 fulfill 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 perfect answer to a numeric issue. This process 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 challenging mathematical problems--that is 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 equal to the target 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 speed," which is measured in terms of megahashes per original site second (MH/s), gigahashes per second (GH/s), and terahashes per second (TH/s).

If you want to estimate how much Bitcoin you could mine with your mining rig's hash rate, the site Cryptocompare provides a very 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--purchase individual graphics cards (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 blocks with whirring circles. Note the sandwich twist-ties holding the pictures cards into the metal pole.

ExampleI tell three friends I'm thinking of a number between 1 and 100, and that 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 just have to be the first person to figure any number that's less than or equal to this number I am thinking of.

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

In Bitcoin conditions, simultaneous answers occur frequently, but at 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%--that miner to honour. Typically, it is the miner who has done the most work, i.e.

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

Now imagine that I present the"figure what number I'm thinking of" question, however I'm not asking only 3 friends, and I'm not thinking of a number between 1 and 100. Rather, I am asking millions of prospective miners and I'm thinking about a 64-digit hexadecimal number. Now you see that it is going to be quite hard to guess the ideal answer.

The number above has 64 digits. Easy enough to understand up to now. As you probably 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 address in the middle 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 every digit has 10 possibilities, 0-9.
