Very transparent and legitimate company in the world of cryptocurrency mining. There are real existing mining farms as proof that they are really in the crypto mining industry. With the partnership with Minebest, the provider of the infrastructure and mining machines, Mining city is the marketing arm of the industry. Rental of hashrate to mine Bitcoin and Bitcoin Vault creates passive and active income for the members. CEO’s and leaders are well known people in the fiend of cryptocurrency. They are very friendly and approachable persons. Kudos to the people behind the company and to the members as well.
