A Beginners Guide To Becoming A Crypto Miner

By Jason Hulott | CryptoCurrency

The simplest ways to get cryptocurrency coins are by either buying them or by accepting them as payment for goods and services. If, however, you want to get involved in the creation of new coins as a miner, you have some options.

Your level of return will vary according to the method you choose and is vulnerable to market movement but almost anyone can give mining a go at some level.

Some parts of this guide are a little technical – sadly we don’t make any bones about that. Crypto is a bit technical. There is a learning curve here and we hope this helps push you up it a bit further than when you started.

Remote Mining

Cloud Mining

You lease computing power from providers who run their own hardware in bulk. These mining farms are found in places with cheap electricity, for example, China or Iceland, to keep their overheads low. Your earnings depend upon how much power you’re leasing and you never own the hardware.

Pros:

  • No noise or heat generated at home
  • No need for technical knowledge regarding mining rig set-ups
  • Power and cooling handled on site
  • Maintenance included in the contract

Cons:

  • No standard of regulation on fees
  • Payout frequency varies according to the provider
  • No requirement to prove they HAVE any hardware
  • Popular contracts sell out fast and have a waiting list

Due diligence: Do your homework for proof that the cloud mining provider is real. Pictures and live feeds from their farms are a good sign. Make sure you know how and what they’ll charge you and when you can expect payouts before you lock yourself into a contract.

Cloud Mining Services

Mining Hosts

You pay a company to house your equipment in temperature-controlled data-centres for a monthly fee. These companies may sell the rigs or allow you to send in your own. The hosting company will normally include minimum uptime standards and regular maintenance in your contract.

Pros:

  • As per Cloud Mining regarding environment and maintenance
  • You keep everything mined by your machine
  • If you want to change host, you can take your equipment with you

Cons:

  • High upfront investment in mining hardware
  • You receive payouts only while paying the fees
  • You’re reliant on the data-centre for physical and data security
  • Factor in transport costs if you need to send your machine in rather than buying from the host

Due diligence: Hosting fees will vary according to what type of rig you are supplying. Always check terms and conditions for minimum uptime standards and what happens to your rig in case of non-payment of fees or catastrophic failure, e.g. fire or flood.

Hosting Service Examples

Mining Rigs

You can build or buy a mining machine for use at home or with a hosting provider. There are two different platforms, ASIC and GPU.

ASIC

This stands for Application-Specific Integrated Circuit – a machine that only does one thing but is superb at that. ASIC machines come pre-built but you will need to add a power supply. Most ASIC machines use the SHA-256 or Scrypt algorithms which mine Bitcoin or Litecoin, respectively. Other coins are available under each form of calculation but you have to stick to the algorithm you purchased, there’s no customisation. Most ASIC miners are available from companies that run mining farms on the same hardware which can lead to availability issues. A web interface lets you add your wallet details for payouts. New iterations can be up to 50% faster than the previous model so the focus is on making a profit as fast as possible. Hence for maximum efficiency, the miners stay active 24/7.

Pros:

  • Fast at mining their set currency
  • Comparatively cheaper than a multi-GPU machine
  • Easy to use
  • Small footprint
  • Self-contained unit needs no additional technical skills to set up

Cons:

  • Noisy; 70db from the fans means that ASIC miners don’t work well in residential space
  • Hot; ventilation is essential and the high-speed chipset pumps out a lot of heat
  • Speedy obsolescence; advances in technology renders previous models worthless and the dedicated hardware means you can’t re-purpose them
  • Limited warranty; normally only 180 days
  • Devices only manufactured and repaired in China

Due diligence: ASIC gives the best rate of return on the right currencies. However, their environmental needs are inconvenient, demanding their own clean, ventilated and ideally soundproofed space. A good option is to make use of a hosting company as above, who are able to handle the needs of ASIC machines in clean spaces, allowing for maximum uptime. If you DO decide to run ASIC rigs at home, then you’ll need a secure and well-ventilated room away from your living space.

Current ASIC Miners

GPU Miners

A mining rig based on GPUs makes use of the calculating ability of retail graphics cards to work through the mathematical problems generating new crypto coinage. Unlike ASIC machines GPU miners require a full computer to work. Although this makes them trickier to set up, they are far more household-friendly than ASICs. GPUs cannot compete with the speed of dedicated ASIC machines and are therefore suitable for coins resistant to being mined with an ASIC rig. ASICs have cornered the market on Bitcoin and its clones but the Ethereum algorithm and its offshoots work better on GPU rigs.

GPU miners broadly fall into two categories; dedicated mining engines and part-timers, general purpose machines which can be used for tasks other than mining, such as games. The initial level of investment can be higher than ASIC machines but GPU rigs have several advantages; being built from retail components they have standard warranties, usually at least 1 year. They also tend to hold their value on the resale market as gamers look for affordable upgrades.

Pros:

  • Upgradeable
  • Good resale value

Cons:

  • GPU miners not capable of effectively mining Bitcoin itself
  • Expensive to initially buy quality components
  • Technical skills are a necessity to set up the system to its best advantage

Due Diligence: GPU mining can be an excellent introduction to cryptocurrency creation but requires more set up and software maintenance than ASICs for a slower return. The potential is there to make a reasonable profit but this needs to be balanced against the costs of power. The versatility of GPU mining is that different software allows you to mine different coins so you can adapt to a changing market and take advantage of new coins as they arise.

Project: Home Building

GPU miners are just specialised PCs at heart. You CAN buy pre-built but you can also put together a reasonable first machine from easily available components. This gives you control over the rig and allows you to upgrade at a later date if you want. You’ll need the following components, a clear space to build and access to one of the many excellent tutorials available online. Or a tech-savvy friend.

  • Case
  • CPU
  • Motherboard
  • RAM (minimum 4gb)
  • SSD; generates less heat and noise than traditional hard drives
  • 1 or more Graphics Cards (GPUs)
  • Power Supply (PSU)
  • Cooling Fans; dependant upon case, 120mm are usually most efficient
  • PCI-E Risers (optional)
  • Operating System (eg Windows)
  • Mining Software; Nicehash is a good starting point that lets you choose the most profitable coin to mine automatically and pays out in Bitcoin

Case: A dedicated miner needs to mount multiple graphics cards; 6 or 8 is considered the sweet spot for the home miner, and that means a frame case. These open structures let you mount multiple GPUs and fans, giving maximum airflow and keeping the cards cooler. They’re unsuitable for use as home PCs as the exposed components mean you’ll want to keep them away from children and pets to avoid damage. Part-time miners can use closed cases housing 1-3 cards but you need to check how big the GPUs are to ensure they’ll fit.

Frame Cases:

Closed Cases:

CPU:

Almost any processor can run a mining rig, they don’t need to be that powerful. However while a 6-GPU machine doesn’t need it, a 1 or 2 GPU part-timer might benefit from the massive L3 cache (fast, on-chip memory) and the high number of cores on the new AMD Ryzen and Threadripper processors. These can effectively give you the power of an additional GPU and although they have a higher upfront cost they stand a good chance of paying for themselves within a year. The choice of CPU will dictate your motherboard options and dedicated miners will have more choice with Intel processors.

AMD:

  • Ryzen Threadripper 1920x; 16 cores give excellent additional mining capability but runs hot and needs an after-market cooler. TR4 chipset
  • Ryzen 5 1600; mid-range chip with 6 cores. Comes with a cooler. AM4 chipset

Intel:

Motherboard:
Dictated by your processor and how many GPUs you’re using. Currently Intel boards are more suited for multi-GPU miners, AMD for general-purpose machines. Key features to look out for are build quality, stability and number of supported GPUs. For Motherboards supporting 6+ GPUs you will need to use “PCIE risers”to connect your motherboard to the GPUs on their frame. For the protection of your components look for risers with 3 or 4 capacitors, the best of which are made in Japan.

Intel:

AMD:

PSU:

Your mining power supply has the greatest potential to damage your system, so look for those rated “Silver” or better. Once you’ve worked out how much power your rig draws by adding up the requirements of the components, factor in another 20% as a safety margin in the PSU capability.

  • EVGA SuperNOVA 1600 T2; industry-best Titanium efficiency rating, delivers 1600w and has 9 GPU power connectors
  • Corsair HX1200i; Gold efficiency, 1200w and 6 connectors, suitable for smaller or lower power miners

GPU:

The very best mining cards have a lot of high speed (DDR5) memory, i.e. 8gb or more. These are the most expensive parts but the modular nature of building a mining PC means that you can add to or upgrade the cards as finances permit.

The home build option is not necessarily the cheapest way to mine coins but for learning about the process and your options it’s hard to beat getting hands-on. The suggested components are very good but you can pull something together with spares you have lying around or picked up 2nd hand that can show you how mining works and if you want to invest in the next step.

Summary

As you can see with coin mining there are a lot of options. You have not missed the boat by any stretch of the imagination. Depending on your current level of knowledge or time you can either join a cloud or remote based mining service, or if you feel up to it you can build your own crypto miner. Whatever you decide we hope this guide has given you some ideas.
