AntMiner is the most well known brand of Bitcoin miners. It is also well regarded, since it has been one of the few Bitcoin miners that has shipped on time.
Bitmain operates Antpool, which since the beginning of 2016 has more hash power than any other mining pool.
Hashnest is a unique cloud mining service: it hosts the mining hardware owned by its customers. This setup eliminates the need for customers to host mining hardware at their own homes or warehouses. Hashnest makes it possible to mine bitcoins without worrying about noise, electricity costs, or excess heat.
The hash power generated by Hashnest is pointed towards Antpool.
Bitmain has also invested in a number of Bitcoin companies, as listed below.
