Bitcoin Mining Hardware

Hobby Bitcoin mining can still be fun and even profitable if you have cheap electricity, an efficient bitcoin mining machine, and get the best Bitcoin mining hardware.

It’s important to remember, however, that Bitcoin mining is competitive and today it is not a good idea for the average person to mine. If you want bitcoins then you are better off buying bitcoins.

What is an ASIC Bitcoin Miner?

Since it’s now impossible to profitably mine Bitcoin with your computer, you’ll need specialized hardware called ASICs.

Originally, Satoshi intended for Bitcoin to be mined on computer CPUs. However, Bitcoin miners discovered they could get more hashing power from graphic cards. Graphic cards were then surpassed by ASICs (Application Specific Integrated Circuits).

Nowadays all serious Bitcoin mining is performed on dedicated Bitcoin mining hardware ASICs, usually in thermally-regulated data-centers with access to low-cost electricity. Think of a Bitcoin ASIC as specialized Bitcoin mining computers, Bitcoin mining machines, or “bitcoin generators”.

Don’t Get Confused

There is Bitcoin mining hardware, which mines bitcoins.

There are also Bitcoin hardware wallets, which store bitcoins.

How to Find the Best Bitcoin Miner

There are some important factors to look at when determining which Bitcoin mining ASIC to buy:

Hash rate – How many hashes per second can the Bitcoin miner make? More hashes cost more, which is why efficiency is crucial…

Efficiency – You’ll want to buy the most efficient bitcoin mining hardware possible. Since miners use a large amount of electricity, you want to buy one that converts the most amount of electricity into bitcoins.

Price – How much does the bitcoin miner cost? Cheap mining hardware will mine less bitcoins, which is why efficiency and electricity usage are important. The fastest and more efficient mining hardware is going to cost more.

Don’t try to buy a miner based on only price or only hash rate. The best ASIC miner is the most efficient bitcoin miner. Aim for value.

Bitcoin Miners for Sale on eBay or Amazon

If you’re a hobby miner who wants to buy a couple rigs for your house, eBay and Amazon both have some decent deals on mining hardware.

Hardware Profitability

You can use a bitcoin mining profitability calculator to determine your estimated cost of return on your mining hardware.

Be sure to take electricity costs into account. Most mining hardware appears profitable until electricity costs are accounted for.

Most Efficient Bitcoin Miners

Good Bitcoin mining hardware needs to have a high hash rate. But, efficiency is just as important.

An efficient Bitcoin miner means that you pay less in electricity costs per hash.

The miners in the table below are currently the most efficient Bitcoin miners on the market.

The Avalon6 gets 0.29 Watts/GH, but costs more than $200 more than the Antminer S7.

The Antminer S7 is more efficient, with 0.25 Watts/GH. The Antminer S7 also costs much less, and comes with 4.5 TH/s of hash power compared to the Avalon6’s 3.50 TH/s.

The AntMiner S7 is clearly the better option between these two miners, which are currently the most efficient miners available for purchase.

To improve your efficiency, there are also companies that will let you order hardware to their warehouse and run the miners for you.

You could also cloud mine bitcoins. But both options are a lot less fun than running your hardware!

Bitcoin Mining Hardware Companies

Bitmain – Bitmain makes the Antminer line of Bitcoin miners. Bitmain is based in China and also operates a mining pool.

BitFury – BitFury is one of the largest producers of Bitcoin mining hardware and chips. Its hardware is not available for purchase.

Spondoolies Tech – Spondoolies Tech is an Israeli based mining hardware manufacturer.

Bitcoin Mining Equipment

In addition to a Bitcoin mining ASIC, you’ll need some other Bitcoin mining equipment:

Power Supply – Bitcoin rigs need special power supplies to funnel and use electricity efficiently.

Cooling Fans – Bitcoin hardware can easily overheat and stop working. Buy a sufficient amount of cooling fans to keep your hardware working.

You can find Bitcoin mining equipment for sale on eBay.

Bitcoin Mining Without Hardware?

It’s still technically possible to mine bitcoins without dedicated mining hardware.

However, you’ll earn less than one penny per month. Mining bitcoins on your computer will do more damage to your computer and won’t earn a profit.

So, it’s not worth it unless you’re just interested to see how the mining process works. You’re best bet is to buy dedicated hardware like the Antminer S7 or Antminer S9.

USB Bitcoin Miners

Using a Bitcoin USB miner with your computer was once a profitable way to mine bitcoins. Today, however, USB miners don’t generate enough hashing power to mine profitably. If you just want to get a Bitcoin miner USB to learn, eBay is a good place to buy a cheap Bitcoin miner.


  1. Thanks very useful information. Ali from dubai

  2. Hello, I can give 7 S9 units, I need money urgently, so I give

  3. Hi, Please tell me something What is the useful life of the equipment S9 vs S7?
    6 months?, 1 year?, 5 years?

  4. How much bitcoins daily can antminer make daily?

  5. Dear Jordan,
    Where can i find a good Farm to locate my Mining machine?
    trustable, safety, Good in price and etc…

    rthank you for sharing brother

  6. Careful, is a SCAM!!!

  7. Buying bitcoins is the EASIEST and FASTEST way to purchase bitcoins.

    read on my lips 😀

  8. Hi, do you know if you can mine bitcoins with Alienware computers?

  9. Hi Jordan,

    Thanks for your website the valuable guidance you’re providing here.

    I have few questions if you can help me and save my time searching :

    1. Can I use Antminer S9 to mine for other cryptocurrency than bitcoin? How can I utilize it to mine other currencies , I know you said only SHA-256 only but what other currencies use SHA-256 other than bitcoin?

    2. Does Anminor S9 need a bitcoin software as you described ? or it has built-in software?

    3. I used Blockchain app wallet on my iOS mobile and I see it taking some % whenever I get my money out of it , Is there any Wallet that is Free ? What do you recommend ?

    4. How do I decide if I mine alone or with a pool ? how do I trust this pool or choose the best one? Can I create my own pool ? I have friends who have the same device for example

    5. Is there any bitcoin minor that is scalable ?( i.e. I add more resources or connected devices to empower it ?

    Many thanks in advance for your support and help

    Dr. Rami AlSahhar

    1. Glad it’s helpful.
      1. Only other SHA-256 coins. Try to see other options.
      2. Yes, it will need mining software.
      3. The fee is miner fee, paid to Bitcoin miners for processing your transaction. No paid to There will be fees in all wallets.
      4. You need a pool unless you have more than 0.5% of total network hash rate.
      5. Only additional miners adds more hash power.

  10. I am probably missing something, but wouldn’t it make more sense to buy 6 S7’s vs 1 S9? The expense is slightly less and the output is significantly more with the former? Is there an efficiency or expense factor I am not taking into consideration?

    1. Yes, S9 is more efficient with electricity use. I think someone in a country with free electricty would not care which they buy, but if electricity costs are a big factor S9 will cost less in electricity cost per hash than s7.

  11. Wow very good explanation , after read through your post , I have an idea which miner to choose , before this i doubt S7 or S9 which is better choice ,
    In conclusion
    Buy S7 if electricity cost low
    Buy S9 if electricity cost high
    at our place
    Thxs bro. Good job

  12. For start up mining/hobby mining would a bundle of S7s be better or save up for a single S9?

  13. Can we mine litecoin using S5 miner and it will be profitable or not please reply

  14. Hello Guys
    thanks for this post, I’ve come accros another miner rig supplier from Taiwan,
    I hope you help me see if its not a scam
    they have an asic miner 20th/s and others about 0.81 BTC
    can you guys check out their website and see if its a scam, I did the best myself but still septic
    best regards

    1. I have not heard of it. I checked the site. Does not have usual look of scam but I would still be very careful.

  15. So a S9 will not enable me to mine for Litecoin the Eth?

  16. Antminer S5 what’s the best power supply for it or which one would you use and where to buy

  17. So is mining still worth in 2017? Especially if my electricity is fee

  18. Do all these miner work for other coins?

  19. I am in Kenya. I am interested in mining via S9. I have free renewable electricity. What is the profitability of one S9 miner if I do pool mining?

  20. What about the “SP45 Newton (BATCH 1) – Spondoolies-Tech”, it’s a good miner?

  21. What electricity power load or power connection is required (like 1 KW or 2 KW) for Antminer S9 and Antminer S7.

    I have 2 KW load at office. Will it be sufficient to run Antminer S9 for the same.

    Is the power efficiency 0.098 J/GH?

    I also want to know that the Bit Mining of Antminer S9 (0.50 BCT per month) is generated by running Antminer S9 for how many hours every day? Is it few hours per day or it has to run non-stop and continuously for 1 month (24 hours a day) to mine (0.50 BCT per month) by Antminer S9

  22. wow, you have to have industrial or commercial electricity to make money, and it will still take 2 years minimum to turn a profit.

  23. Help I want to buy an antminer (s7 / s9 / r4) I would like to know how to make it work correctly, could you contact my mail? Thank you
