Cryptocurrency mining in a shipping container
Cryptocurrency mining in a shipping container refers to a modern, highly specialized and mobile solution for efficiently running large-scale mining operations. It is usually a standardized steel container (most often 20 or 40 feet), which is carefully adapted to function as a self-sufficient, portable data center designed exclusively for cryptomining – the mining of cryptocurrencies such as Bitcoin, Ethereum, Kaspa, Litecoin or Dogecoin.
The concept of the mining container (also crypto container, crypto mining shipping container, mobile mining unit, containerized mining farm) emerged as a response to the growing energy and infrastructure demands of industrial cryptocurrency mining. Instead of building expensive, static infrastructure, the robustness and mobility of containers allow rapid deployment, easy scaling and a reduction in operating and investment costs. These units are designed to optimize performance, minimize operating expenses, enable rapid deployment on a global scale and are often intended for connection to renewable energy sources.
Detailed description and operating principle
Structure and function of a mining container:
- Basic frame: The container is made of highly durable steel (often Corten), which ensures a long service life even in demanding climatic conditions. Standard dimensions are 20 feet (approx. 6.1 m) or 40 feet (approx. 12.2 m) in length, width 2.44 m, height 2.59 m (high-cube up to 2.90 m).
- Complete conversion: The container is equipped with industrial ventilation, air intake and exhaust openings, filtration systems, cable glands, internal racks and special mounts for placing hundreds of pieces of mining hardware (ASIC and GPU).
- Electrical infrastructure: A robust distribution network includes transformers, distribution boards, circuit breakers, high-power power distribution units (PDUs), power consumption metering, surge protection and options for remote monitoring. A typical connection is 400/480 V, often up to 600 kW for a 20-foot container, and over 1 MW for 40-foot units.
- Cooling: Selected according to hardware and location – from high-performance industrial fans (air cooled), through hydro cooling to state-of-the-art immersion cooling with dielectric fluid.
- Network infrastructure: High-speed Ethernet, backup 4G/5G or satellite connection, real-time monitoring, remote management.
- Security: Reinforced doors, alarms, CCTV, motion monitoring, and possibly physical security.
Operating principle (scheme):
- Preparation and modification of the container: Construction and technical adaptation tailored to the required hardware and chosen cooling type.
- Installation of electrical and network distribution: High-performance PDUs, distribution boards, monitoring, backup power sources.
- Hardware installation: Insertion of ASIC or GPU miners (e.g. Bitmain Antminer S19, WhatsMiner, Innosilicon, Canaan Avalon).
- Cooling and filtration: Installation of fans, possibly coolant, filtration systems (G4/M5 panels, size 592×592 mm, etc.).
- Remote monitoring and management: Management software, monitoring of temperatures, consumption and performance.
- Connection at deployment site: Electrical connection, network connection, possibly connection to renewable energy sources.
Typical technical parameters and variants
| Type of container | Dimensions | Miner capacity (ASIC) | Max. power input | Cooling | Price (approx.) |
|---|---|---|---|---|---|
| Standard 20ft | 6.1×2.44×2.59 m | 120–162 pcs (Antminer S19) | up to 600 kW | Air/Hydro/Immersion | 45,000 – 150,000 USD |
| Standard 40ft | 12.2×2.44×2.59 m | 250–350 pcs (Antminer S19) | up to 1.2 MW | Air/Hydro/Immersion | 80,000 – 300,000 USD |
