What Our Customer Say

Kristin Watson

Affordable Hardware with Good Customer Service

answered all of my questions and made it easy to conduct business with them. Deliveries came faster than expected as well. US buyers, be sure to budget in money for Tarifs, but Asic pricepoint made it still cheaper than many competitors in the US.

Ronald Richards

Buying my miner was quick and easy and shipping was quick

Purchasing my first miner was very easy and shipping was quick. They answered any questions I had about the products I was interested in. I was so pleased with my first purchase from them that I have entrusted them with a rather sizable order this time around.

Wade Warren

First of all, Asic Miner World is not a scam and neither am I
Second, Global Miner World takes credit cards.
Third, the team at AMW is friendly and professional.
Im a small fish in the mining business right now and all these things matter to me.

Aviana Plummer

My experience with this company was excellent. Great customer support, both text and email. Due to something beyond their control, the miner I originally ordered was delayed. They said they would compensate me and they and gave me a SWEET upgrade deal (at my request) at the lowest price on their waiting list and bumped me to the head of the line. I will do business with them again. Credible company. Highly recommended!

TECHNICAL

The profitability of each miner (per day) can be checked here.

Q2: “What power cable will I need for my miner?”

All ASIC miners sold by We (new and used) are provided with their original, manufacturer-provided power supply cables and therefore they are fit for the use with Chinese power outlets only.

However, power cables suitable for European, UK, American or any other type of power sockets can be easily purchased online or at most electronics stores.

Below you can see which power supply cable is necessary for each type of ASIC miner:

C13 16-20amp Power Cable:

1) Bitmain
2) Innosilicon.

C19 16-20amp Power Cable:
1) Canaan
2) Goldshell (apart from Goldshell Mini-Box miners which need C13 power cables).
3) Whatsminer.
4) StrongU.

Q3: “Should I contact We support team before disassembling the miner?”

Absolutely. To ensure your warranty for the miner isn’t breached, please send us an email before disassembling the miner.
In your email, please give us your order number, describe the problem and provide the serial number of the affected miner.

Full warranty details can be viewed here: https://agminer.com/maintenance-policies/

Q4: “Where can I find user manual or user guide for my ordered miner?”

Please send us a quick email and we will provide you with all of the documentation you require.

Q5: “What set-up would you recommend for a home/office and would you be able to help me set-up?”

We can provide you with full assistance from setting up to troubleshooting.

All of our miners are very simple to set up and are nearly ready to go from the box.

You will need to make sure you have an Ethernet cable to plug your miner into your router and the correct power cord.

For most miners, there is a user manual to assist with setting up, but if required, we are more than happy to assist.

Q6: “What should I do or prepare before receiving the miner?”

In order to provide the necessary conditions for successful operation of the miner, we would advise you to prepare a stable network and power supply as well as a ventilated environment. Once this is done, you may wish to review the user guide, apply for a mining pool account and watch some tutorials relevant to your specific miner.

Q7: “How long will my new unit be profitable?”

ASIC miners are built for longevity. Therefore, most miners will continue to be usable for years to come and provide profitability in the foreseeable future. Please take into consideration the profitability of ASIC miners is impacted by a number of things including: the mineable coins value, the power consumption and hashrate.

Q8: “Do I need a high speed Wi-Fi connection to be able to mine?”

The bandwidth of your crypto mining will depend on some factors. Traditionally, crypto mining does not use a lot of bandwidth. There is no specific amount of bandwidth crypto mining uses. But, at an average, if you’re mining on your own, you will need a bandwidth speed of 15kbps for inbound transactions and 12kbps for outgoing transactions.

Q9: “What are the first mistakes that I should be wary of as a beginner miner?”

When running an ASIC miner please make sure you have the right environmental conditions. Some small miners such as the Goldshell KD-box, Dogecoin Mini, SC Box miners are built for use at home or the office. However, if you are running a larger and more powerful ASIC miner at home you would need to make sure you have ventilation and cooling systems in place to stop the miner from overheating. This way you can reduce your downtime and keep the miner running and profitable throughout the year.
