Weaker bitcoin prices and rising mining difficulty have claimed one of the most prominent mining pools as their next victim.
“Mining with using User’s Gigahashes can be stopped by CEX.IO if the amount of the Maintenance Cost exceeds rewards for each mined block or if the mining is economically inexpedient.”

The suspension will take place upon the next difficulty change, which will happen within a few hours. Members will retain their legal rights to hash power, the blog continuing: “Thereby, all GHS formerly purchased by CEX.IO users remain their absolute property, with appropriate figures reflected in users’ profile balance. Additionally users will be able to manually enable mining with Gigahashes by their own choice.”
Jeffrey Smith, Chief Information Officer, explained that the suspension was only temporary and that service will resume once more economical hardware was procured:
“Suspension of CEX.IO cloud mining service is only a forced temporary measure, the result of cloud mining costs exceeding mining profit,” “Currently all cloud mining/maintenance costs are directed to the Hardware provider, hence, we are open for negotiations with additional mining hardware providers, who can offer favourable terms. And, as soon as we get an opportunity to upgrade mining hardware, or come to more efficient terms with energy suppliers, cloud mining process will be automatically resumed.”
Ghash currently commands 42 PH/s, or 12%, of the total network hashrate. Their sudden exit from the network will have a meaningful effect on the total hashrate and possibly lead to another difficulty decrease during the following readjustment period.
