# All About Bitcoin Trading History

Let's say you had one legit $20 and one quite good photocopy of that same $20. If someone were to try to spend both the real bill and the imitation one, someone that took the problem of looking at either of the invoices' serial numbers would observe that they were the exact same number, and consequently one of them needed to be fictitious.

This isn't a perfect analogy--we will 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 established by Satoshi Nakamoto, and can be a matter of controversy, as some miners believe the block size ought to be increased to accommodate more information.

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

1MB of transactions can theoretically be as little as 1 transaction (although this is not at all common) or a few thousand. It depends on how much information 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 have to be the first miner to arrive at the perfect answer to some numeric problem. This practice is also known as a proof of work.

The fantastic news: No advanced math or computation is involved. You might have discovered 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") 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 rate," which 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 how much Bitcoin you can mine along with your mining rig's hash rate, the site Cryptocompare offers a 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--buy individual graphics cards (GPUs) as a low-cost way 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 the metal pole.

Case in point : I tell three friends I'm thinking about 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 have 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 this number I'm thinking of.

Let's say I am thinking about 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 theoretically arrived at viable answers, because 16<19 and 12<19. There is no"extra credit" for Friend B, even though B's answer was nearer to the goal answer of 19. .

In Bitcoin conditions, simultaneous answers happen frequently, but at the end of the day there can only be one winning answer. When multiple simultaneous answers are presented like this which can be equal to or less than the target number, the Bitcoin network will decide by a simple majority--51%--which miner to honour. Typically, it's the miner who has done the work, i.e.

## 3 Simple Techniques For Bitcoin Trading History

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 this alphabet. Why is that

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