# The smart Trick of Master Coin That Nobody is Discussing

In 2009, it was 50. In 2013, it was 25, at the time of writing it is 12.5, and sometime in the middle of 2020 it will halve to 6.25. .

At this speed of halving, the entire number of bitcoin in circulation will approach a limit of 21 million, making the currency more scarce and valuable over time but also more costly for miners to produce.

Here is the catch. In order to get bitcoin miners to really earn bitcoin from verifying transactions, two things have to happen. First, they need to verify 1 megabyte (MB) worth of transactions, which can theoretically be as little as 1 transaction but are far more often several thousand, depending on how much information each transaction shops.

Second, in order to put in a block of transactions to the blockchain, miners should fix a complex computational math problem, also called a"proof of labour " What they're actually doing is trying to come up with a 64-digit hexadecimal number, called a"hash," that is less than or equal to the hash.

In other words, it is a gamble. .

The difficulty level of the most recent block at the time of writing is about 7,184,404,942,701. That is, the chance of a computer producing a hash beneath the goal is 1 in 7,184,404,942,701 less than 1 in 7 trillion. That level is corrected every 2016 blocks, or about every two weeks, with the goal of keeping rates of mining constant.

The opposite is also true. If computational power has been taken off of this network, the problem adjusts downward to make mining simpler. .

"Say I tell three friends 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 have to guess the specific number, they simply must be the very first person to figure any number that's less than or equal to this number I'm thinking of.

"Let's say I'm thinking of the number 19. If Friend A guesses 21, they lose because 21>19. If Friend B guesses 16 Recommended Site and Friend C guesses 12, then they've both theoretically arrived 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 target answer of 19. .

"Now imagine I present the'imagine what number I get redirected here am thinking of' question, however I am not asking just 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 is going to be quite difficult to guess the ideal answer." .

If 1 in seven trillion doesn't sound hard enough as is, here's the catch to the grab. Not only do bitcoin miners have to think of the ideal hash, they also have to be the very first to perform it.

Since bitcoin mining is essentially guesswork, arriving at the right answer before another miner has everything to do with how fast your computer can produce hashes. Only a decade ago, bitcoin miners can be carried out competitively on normal desktop computers. As time passes, however, miners realized that pictures cards commonly used for video games tend to be more effective at mining than desktops and graphics processing units (GPU) came to dominate the match.

These can run from \$500 to the tens of thousands. .

Today, bitcoin mining is so competitive that it can only be done profitably using all the latest up-to-date ASICs. When using desktop computers, GPUs, or elderly versions of ASICs, the expense of energy consumption actually surpasses the revenue generated. Even with the newest unit available, one pc is rarely enough to compete with what what miners call"mining pools." .

An mining pool is a group of miners that combine their computing ability and divide the mined bitcoin between participants. A disproportionately high number of blocks are mined by pools rather than by individual miners. In July 2017, mining pools and companies represented approximately 80% to 90% of bitcoin computing power. .

Between 1 in 7 trillion chances, scaling difficulty levels, and the massive network of consumers verifying transactions, one block of transactions is confirmed roughly every 10 minutes. But its important to remember that 10 minutes is a target, not a guideline.
