# The 3-Minute Rule for How To Make Money Through Blogging

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 fake one, someone who took the problem of looking at either of the bills' consecutive numbers would see that they had been the exact same number, and thus 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) worthiness of Bitcoin transactions, they are entitled to win the 12.5 BTC. The 1 MB limit was set by Satoshi Nakamoto, and is a matter of controversy, as some miners think the block size should be increased to accommodate more data.

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

1MB of transactions can theoretically be as small as 1 transaction (though this is not in any way common) or several thousand. It depends on how much information the transactions take up.

In order to earn Bitcoin, you need to meet two conditions. One is a matter of effort, one is a matter of luck.

2) You must be the first miner to arrive at the perfect answer to a numeric problem. This practice 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 difficult mathematical problems--that is not true at all. What they are doing is trying to be the first miner to think of a 64-digit hexadecimal number (a"hash") which is less than or equivalent to the hash.

The bad news: Because it is guesswork, you need a good deal of computing power in order to get there . To mine , you need to have a higher"hash speed," 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 could mine along with your mining rig's hash read this post here pace, the site 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 to the tens of thousands. Some miners--especially Ethereum miners--buy individual graphics cards (GPUs) as a cheap method to cobble together mining operations. The photo below is a makeshift, home-made mining machine. The cards are such rectangular blocks with whirring circles. Note the sandwich twist-ties holding the graphics cards into the metal pole.

Example: I tell three friends that I'm thinking of a number between 1 and 100, and I write that number on a sheet of paper and seal it in an envelope. My friends don't need to guess the specific number, they just must be the very first person to guess any number that is less than or equal to the number I'm thinking of.

Let us 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've both technically came 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 target 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 equivalent to or less than the target number, the Bitcoin network will decide by a simple majority--51%--that miner to honour. Typically, it's the miner who has done the work, i.e.

The losing block then becomes an"orphan block" .

Now imagine that I pose the"guess click over here what number I'm thinking of" question, but I'm not asking just three friends, and I'm not thinking of a number between 1 and 100. Instead, I'm asking millions of prospective miners and I am thinking of a 64-digit hexadecimal number. Now you see that it is going to be extremely difficult to guess the ideal answer.

## 9 Simple Techniques For Bitcoin Trading History

The number above has 64 digits. Easy enough to understand up to now. As you probably noticed, that number go now 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 middle of numbers, let's unpack the term"hexadecimal."

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