Genesis Mining is a popular cloud based Bitcoin mining platform that lets users mine for Bitcoin. Each user is placed on a contract, through which they are allocated provisions in order to be able to mine through the platform, differing platforms offer differing rewards but of course, the bigger the reward the more expensive the contract, therefore, Genesis Mining have had to make some cut backs in order to ensure that those on the big contracts still have access to the service, as a result of the collapsing value of Bitcoin.
