# How to build a cryptocurrency mining rig?

Redwan Eid | Jul. 16, 2019

July 16, 2019 | AtoZ MarketsThere are three types of cryptocurrency mining rigs, each of which is more expensive and more powerful than the previous one. This article comes to identify each type and method of preparation of each of them, and we will talk about how they operate.

In this article, we will learn about the mechanics dedicated for mining Bitcoin and what is the process of mining. We will also move from the theoretical side to the practical and applied ones.

How can you prepare a mining machine for Bitcoin and then start the mining process?

The first thing you do is choose your mining devices, and there are two main points to think about when coming to this part.

## Hash Rate – what is the hash rate?

Hash is the number of calculations your mining rig performs per second while, trying to solve the mathematical equation.

The hash rate is calculated in units of megahashes - gigahashes - terahashes per second (MH / sec, GH / sec, TH / sec) the higher the rate of the production of Hash, the greater the probability of solving Block Equations.

## Bitcoin average power consumption

All this computational power to solve the equations consumes high electrical energy, thus increasing the financial cost, so before choosing the mining rig, you should know its consumption of electricity in watts, when you make sure you will not spend all your money on electricity instead of earning more money from the mining process.

Using the above-mentioned factors, you can calculate the amount of heat generated per electricity consumption of electricity by dividing the resulting hash into electricity consumed by hashes / watts.

Example: If your device is producing 500 GH / Sec and consumes electricity at 400 watts, if you get 1.25 GH / Sec you can calculate the electricity consumed from the electricity bill or there are websites that calculate this for each device.

There is a warning here that in some cases you will use your own computer to operate the mining rig, then the consumption of the computer will add to the electricity consumption of the mining device, so you should take this into account during your calculations.

## The Bitcoin mining rig parts

We can split mining devices into three sections, using mining: (GPUs, FPGAs, ASICs) We will review each type below.

• ### Bitcoin mining using graphics cards or computer CPU/GPU processor

Your PC is one of the weakest ways to mine Bitcoin. In theory, you can use your CPU to mine bitcoin, but in practice, it is a weak way because of other considerations.

You can increase the output rate of Hash with the addition of a powerful graphics card for your device, as the graphics cards GPU designed to solve too complex mathematical equations to be able to show the models clearly and high-quality video games. This makes them suitable to solve the equations and calculations for the production of Hash from each block.

You can buy graphics cards from two major companies, AMD and Nividia. High-quality graphics cards cost hundreds of dollars, but give you remarkable advantages instead of producing Hash using a CPU.

One of the best things to use GPU graphics cards in mining is that they give you options to control the mining process, unlike other methods as we will mention later.

We can use graphics cards in mining electronic currencies other than Bitcoin, for example, Litcoin uses a different method than Bitcoin to prove the proof of work, namely script. This method is designed to fit mining using graphics cards GPU and CPU processor, making mining using graphics cards is a good option for those who move between mining different currencies.

GPU-based mining is largely disappearing these days, because the difficulty of Bitcoin mining has increased dramatically with the release of ASIC devices that graphics cards cannot compete with.

• ### Bitcoin mining using FPGA circuits

The term FPGA is a shortcut to the Field Programmable Gate Array, which is a programmable logic gate array, which is an integrated circuit, designed to be prepared after it is built, because of its programmability. This makes the mining equipment manufacturers buy it in large quantities (due to their scalability and modification) and then prepare it for the mining process before placing it in their devices Special. After the preparation of the mining process, it performs a performance that surpasses the use of graphics cards or computer processor; each slice can produce about 750MH / sec and of course, for high-quality products and it is possible to put more than one chip within a single device.
