Antminer A3 Colocation

The Antminer A3 is a cryptocurrency miner developed by Bitmain. Unlike most other Antminer models, it’s designed to mine Siacoin instead of Bitcoin. As it has a good hash rate and is available for immediate delivery, it has become quite popular among cryptocurrency miners looking for a way to diversify their portfolio by mining coins other than Bitcoin.

Those interested in getting an Antminer have several ways of getting their hands on one. New units can be purchased directly from Bitmain at their online shop. However, the manufacturer limits the number of units sold to each customer in an effort to give more miners the chance to get one. Both new and used units are available on online marketplaces like eBay and Amazon as well. On average, someone purchasing the Antminer A3 will need to spend $1,900 for one unit. Just like with other Antminer devices, miners will need to purchase the power supply separately.

Is getting an Antminer A3 a good idea? Here is an overview of the main advantages and disadvantages of this device:


  • Easy to buy online and delivered quickly with minimal waiting times.
  • Allows you to diversify your cryptocurrency mining activities, giving you the chance to mine other crypto coins than Bitcoin.
  • Simple to get up and running and reliable.
  • Offers decent ROI with most of the mining pools available today.


  • The powerful cooling fan makes it quite loud when it operates.
  • Just like other Antminer models, it uses a lot of electricity.
  • Mining any cryptocurrency involves making risky investments due to market volatility.

Antminer A3 Colocation Hosting Services

As the number of units each individual miner can buy are limited by Bitmain for the time being, most people mining with the A3 have just one or two units running in their home or office. If one has relatively affordable electricity and doesn’t mind the noise created by the miners, hosting them at home can be a good option.

However, many miners who purchased the A3 intend to use them along with other Antminer models, like the L3+ and S9. Those who have several miners should consider placing them in an outsourced data center that allows cryptocurrency miners. Antminer colocation services offer quality rack space, electricity, cooling, security and an Internet connection so that your miner can keep on running 24 hours a day, 7 days a week. Every since the popularity of cryptocurrency mining has taken off, many companies began offering specialized Antminer A3 colocation hosting. Prices in North America currently range from $105 to $140 per month. However, they can change over time due to supply and demand.
