# The Facts About Bitcoin Trading History Revealed

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 real bill and the imitation one, someone that took the trouble of looking at either of those bills' serial numbers would see that they were exactly the exact same number, and consequently one of them had to be fictitious.

That 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 can be an issue of controversy, as some miners believe the block size should be increased to accommodate more data.

Note that I said that verifying 1 MB worth of transactions makes a miner qualified to earn Bitcoin--not everyone who supports transactions will receive paid off.

1MB of transactions can technically be 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 must be the first miner to arrive at the perfect answer to a numeric problem. This process is also known as a proof of work.

The fantastic 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 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: Because it's guesswork, you need a good deal of computing power in order to get there . To mine successfully, you need to have a higher"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 pace, the website Cryptocompare offers a very 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--particularly Help Wikipedia Ethereum miners--purchase 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 those rectangular blocks with whirring circles. Note the sandwich twist-ties holding the graphics cards to look here the metal rod.

Case in point : I tell three friends 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. My friends don't have to guess the specific number, they simply must be the very first person to guess any number that's less than or equal to this number I'm thinking of.

Let us say I'm thinking about the number 19. If Friend A guesses 21they shed because 21>19. If Friend B guesses 16 and Friend C supposes 12, then they have both technically came at workable answers, since 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 conditions, simultaneous answers happen frequently, but in 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 determine by a simple majority--51%--that miner to honour. Normally, it's the miner that has done the 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, however I am not asking only 3 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's going to be extremely difficult to guess the right answer.

## Getting The How Bitcoins Are Made To Work

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 the alphabet. Why is that

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

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