About Giga Hash

Giga Hash Ltd is a registered company in Bulgaria. The Eastern European startup begin its cloud mining activity in December 2013, so they were one of the first on the market. As an anecdote, they share with the public, that the idea to setup a cloud mining company is came from local investor’s desire to invest into cryptocurrencies who does not have technical knowledge of mining hardware. Particularly, a sailor wanted to invest into bitcoin without owning the associated mining equipment.

The owners and founders of the company is not listed in their About section. Ironically, because of the name of the company it is fairly difficult to find some relevant information on the internet about them as searching for the term Giga Hash mostly results millions of pages in the crypto world. The company is associated with Tihomir Ganev. Mr Ganevhas multiple website registered under his name and only lists webmaster experience on his presumed Linkedin profile.

The company  is using the latest ASIC mining hardware for mining bitcoin and altcoins, but the exact types of miners are not specified on the website, probably they are using Antminers based on the news on the site.  Due to security reasons, the company does not wish to disclose the exact location of the mining facility, the farm is in Varna, Bulgaria. However there is no picture on the site about the mining equipment or about the farm, so it is difficult to see how big is the scale on which they are working on.

Because of the rising bitcoin difficulty, Giga Hash stopped selling bitcoin cloud mining contracts as it is no longer profitable at current electricity and other costs. In May 2016 the maintenance costs were $1.17 on the Antminer S5 devices, while the mining only resulted $1.16, so they terminated the contracts at the subsequent bitcoin reward halving. With current bitcoin prices it is not likely that they will go back online with bitcoin mining unless they upgrade the mining equipment. Now they are only focusing on the mining of scrypt coins.
