Bitmine Review: A Serious Bitcoin Mining Company


Headquartered in Switzerland, Bitmine AG is a developer and manufacturer of Bitcoin mining related materials.

Bitcoin as you should know by now,  is a peer-to-peer, open source digital currency and payment network. It uses cryptocurrency, a digital medium of exchange. A Bitcoin miner utilizes software to resolve math problems and receive a specific number of bitcoins in return. This is a way to manage cyptocurrency and create incentive for continued mining.

Bitmine encompasses a team of experienced technicians with extensive backgrounds in electronics and IT. Since their founding in 2010, the company has produced prototypes of Bitcoin miners. Initially working with GPUs and going through some FPGA mining prototypes, the company has now turned to the Avalon A3256Q48 ASIC mining chip. Bitmine is also hard at work on generating a proprietary and unique high performance ASIC mining chip.

Bitmine Reputation

The team at Bitmine has consistently proven their talent and determination to make a product that stands out in the industry. They have also produced accurate and realistic release dates through strategic planning and stocking of necessary components. To maintain and exceed expectations, Bitmine utilizes in-house production for its mining manufacture. This allows them to keep stringent controls in place and produce one quality product after another on deadline every time!

It is important to Bitmine to maintain an accurate planning schedule. They always want to be able to report that they fully respect and follow through on delivery terms. Continuously altering delivery plans is an annoyance to clients and damages the brand. This is why they compile as much detail as possible before beginning the project’s production. That way there is less likely the chance of a misstep along the way. Bitmine instills their confidence in their delivery terms as all Coincraft based products are guaranteed through their Customer Protection Plan.
