On twentieth July hashflare declared in an email to their clients and on Hashflare's Facebook page that they are no longer going to mine Bitcoin as it is not profitable for them. They also canceled active BTC mining contract of their clients.
Here the official statement from them
So far this whole situation seems like an exit plan. This whole thing started on September 2017 when they had reduced the length of Mining contracts from lifetime to only 1 year. Customers had lost their trust on Hashflare from then but still it seemed legit cause they were still paying their customers. There is nothing to do now but if you had invested your money in hashflare you can contact your bank and ask them to do a chargeback of that particular transaction.
I hope you guys will find a way from this bullshit and from now on I no longer recommend any Cloud Mining site. I would recommend using hardware to mine crypto.
