In 2009, it had been 50. In 2013, it had been 25, in the time of writing it's 12.5, and sometime in the center of 2020 it will halve to 6.25. .

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

Here is the catch. In order for bitcoin miners to actually earn bitcoin from verifying transactions, two things have to occur. To begin with, they need to verify 1 megabyte (MB) worth of transactions, which can technically be as little as 1 transaction but are far more often a few thousand, depending on how much data each transaction stores.

Second, in order to add a block of transactions to the blockchain, miners should solve a complex computational math problem, also called a"proof of labour ." What they're doing is trying to think of a 64-digit hexadecimal number, called a"hash," that is less than or equivalent to the hash.

In other words, it's 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 pc producing a hash beneath the goal is 1 in 7,184,404,942,701 less than 1 in 7 trillion. That amount is adjusted every 2016 blocks, or roughly every 2 weeks, with the aim of keeping rates of mining constant.

The reverse is also correct. If computational power is taken from the network, the problem adjusts downward to make mining easier. .

"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 just have to be the first person to guess any number that's less than or equal get more to the number I'm thinking of.

"Let's say I'm thinking of the number 19. If Friend A guesses 21they shed 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's no'extra credit' for Friend B, even though B's answer was closer to the goal answer of 19. .

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

If 1 in seven trillion doesn't sound difficult enough as is, here is the grab to the grab. Not only do bitcoin miners need to think of the right hash, they also must be the very first to perform it.

Since bitcoin mining is essentially guesswork, arriving at the ideal 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 desktops. As time passes, however, miners recognized that graphics cards commonly used for video games were more effective at mining than desktops and graphics processing units (GPU) came to dominate the game.

These can run from $500 into the tens of thousands. .

Today, bitcoin mining is so aggressive that it can only be done profitably using the most 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 at your disposal, one pc is rarely enough to compete with what what miners call"mining pools" .

An mining pool is a group of miners who combine their computing power and split the mined bitcoin between participants. A disproportionately high number of cubes 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 odds, scaling difficulty levels, and the huge network of users verifying transactions, one block of transactions is verified roughly every 10 minutes. But its important to keep in mind that 10 minutes is a target, not a rule.

More About Is Bitcoin Mining Profitable

The bitcoin network can process about seven transactions per second, with transactions being logged in the blockchain every 10 minutes. Since the network of bitcoin users continues to grow, however, the number of transactions made in 10 minutes will eventually exceed the number of transactions that can be processed in 10 minutes.
