# The Only Guide for Trading Bitcoin Futures

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's the catch. In order for bitcoin miners to really earn bitcoin from verifying transactions, two things have to happen. To begin with, they need to confirm 1 megabyte (MB) value of transactions, which can theoretically be as little as 1 transaction but are more often a few thousand, depending on how much data each transaction stores.

# Getting The Is Bitcoin Mining Profitable To Work

Second, in order to add a block of transactions to the blockchain, miners must fix a complex computational science difficulty, also called a"proof of work." What they are actually doing is trying to think of a 64-digit hexadecimal number, called a"hash," that's less than or equivalent to the hash.

In other words, it's a bet. .

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 target is 1 in 7,184,404,942,701 less than 1 in seven trillion. That amount is adjusted every 2016 blocks, or about every two weeks, with the goal of keeping rates of mining constant.

The reverse is also true. If computational power is taken off of the network, the difficulty adjusts downward to earn mining simpler. .

"Say I tell three friends that 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 specific number, they just have to be the first person to figure any number that is 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 21, they lose because 21>19. If Friend B guesses 16 and Friend C guesses 12, then they have both theoretically arrived at viable answers, since 16<19 and 12<19. There's no'extra credit' for Friend B, even though B's answer was nearer to the target answer of 19. .

"Now imagine that I present the'guess what number I am thinking of' question, but I'm not asking just 3 friends, and I am not thinking of a number between 1 and 100. Rather, I am asking millions of prospective miners and I'm thinking of a 64-digit hexadecimal number. Now you see that it's going to be quite difficult to guess the right answer." .

If 1 in 7 trillion doesn't sound hard enough as is, here is the grab to the grab. Not only do bitcoin miners have to think of the ideal hash, they also get more must be the very first to do 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. Just a decade ago, bitcoin miners can be carried out competitively on normal desktops. 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 game.

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

Nowadays, bitcoin mining is so competitive that 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 consumption actually surpasses the revenue generated. Even with the newest unit available, one computer is seldom enough site web to compete with exactly what miners call"mining pools" .

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

### Trading Bitcoin Futures - An Overview

Between 1 in 7 trillion odds, scaling difficulty levels, and also the massive network of users verifying transactions, one block of transactions is confirmed roughly every 10 minutes. However, its important to remember that 10 minutes is a goal, not a rule.

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.
