# Trading Bitcoin Futures - An Overview

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

At this rate of halving, the entire 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's the catch. In order to get bitcoin miners to really earn bitcoin from verifying transactions, two things must occur. First, they need to confirm 1 megabyte (MB) value of transactions, which can technically be as little as 1 transaction but are more often several thousand, depending on how much data each transaction shops.

Second, in order to add a block of transactions to the blockchain, miners should fix 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, known as a"hash," that's 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. In other words, the chance of a computer producing a hash beneath the target is just 1 in 7,184,404,942,701 less than 1 in 7 trillion. That amount is corrected every 2016 blocks, or roughly every 2 weeks, with the aim of keeping rates of mining constant.

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

"Say I tell three friends that I'm thinking about 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 exact number, they just must be the very first person to guess any number that's less than or equal to this number I am thinking of.

"Let's say I am thinking about the number 19. If Friend A guesses 21they shed because 21>19. If Friend B guesses 16 and Friend C guesses 12, then they have 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 target answer of 19. .

"Now imagine that I pose the'imagine what number I am 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 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 ideal answer." .

If 1 in 7 trillion doesn't sound difficult enough as is, here's the catch to the catch. Not only do bitcoin miners have to think of the ideal hash, but they also must be the first to do it.

Since bitcoin mining is essentially guesswork, arriving at the ideal answer before another miner has almost everything to do with how fast your computer can create hashes. Just a decade ago, bitcoin miners can be performed competitively on normal desktops. As time passes, however, miners realized that pictures cards commonly utilized for video games were more effective at mining than desktops and graphics processing units (GPU) came to dominate the match.

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

Nowadays, bitcoin mining is so aggressive it can only be done profitably using the most up-to-date ASICs. When using desktop computers, GPUs, or older models of ASICs, the cost of energy like it consumption actually exceeds the revenue generated. Even with the newest unit at your disposal, one pc is seldom enough to compete with exactly 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 cubes are mined by pools rather than by individual miners. In July 2017, mining pools and companies represented roughly 80% to 90% of bitcoin computing power. .

Between 1 in 7 trillion odds, scaling difficulty levels, and the massive network of users 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.

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 consumers continues to grow, however, the number of transactions made in 10 minutes will eventually exceed the number of transactions which can be processed in 10 minutes.
