# Bitcoin Trading History Fundamentals Explained

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 real bill and the fake one, someone who took the problem of looking at either of the bills' consecutive numbers would see that they were the same number, and consequently one of them had to be false.

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

Once a miner has verified 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 should be increased to accommodate more data.

Note that I stated that verifying 1 MB value of transactions makes a miner eligible to earn Bitcoin--not everyone who verifies transactions will receive paid off.

1MB of transactions can theoretically be as small 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 fulfill two conditions. One is a matter of work, one is a matter of luck.

2) You have to be the first miner to arrive at 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 heard that miners are solving challenging mathematical problems--that's not true in any way. What they're doing is trying to be the first miner to come up with a 64-digit hexadecimal number (a"hash")  which is less than or equal to the hash.

# The Basic Principles Of Money To Bitcoin

The bad news: Because it is guesswork, you need a good deal of computing power in order to see get there first. To mine , 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 how much Bitcoin you can mine along with your mining rig's hash pace, the website Cryptocompare provides a very helpful calculator.

Either 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--especially Ethereum miners--buy individual graphics cards (GPUs) as a cheap 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 to the metal pole.

Case in point I tell three friends that I'm thinking about a number between 1 and 100, and that I write that number on a sheet of paper and seal it in an envelope. My friends don't need to guess the exact number, they simply have to be the very first person to figure any number that is less than or equal to the number I'm thinking of.

## A Biased View of How Bitcoins Are Made

Let us say I am thinking of the number 19. If Friend A guesses 21they lose because 21>19. If Friend B supposes 16 and Friend C supposes 12, then they've both technically came 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 goal 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 anonymous can be equal 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 that 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 am thinking of" question, but I am not asking only three friends, and I'm 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's going to be extremely difficult to guess the right answer.

## The How Bitcoins Are Made Statements

The number above has 64 digits. Easy enough to understand so far. As you probably noticed, that number consists not only of numbers, but also letters of this alphabet. Why is that

In order to understand these letters are doing in the center of numbers, let us unpack the word"hexadecimal."

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