Dear customers,
Recently we've been updating our website and then our server was down for a while. Due to those reasons we have been unable to process some of the orders in a timely fashion.
And due to the reasons described above and a large number of orders as well as the upcoming holidays in December, all orders are currently processing with a delay.
If you have any difficulties with your order or payment confirmation, please send us an email at [email protected]. Please, be sure to include your order number in the subject line and briefly describe your problem. Our specialists will get back to you with a response as soon as possible.
We apologize for the inconvenience.
Thanks for your patience.
Sincerely yours,
BitmainMasters team
