any one can tell me that gawminer is trusted or not i want to buy s4 antminer from gawminer...can i buy without any problem..thankyou
It is risky , so if you do decide to purchase one use a credit card and get ready for a chargeback.
Many of the employees have left and you may be screwed just because of incompetence alone without any intention of theft.
Immediately test the s4 as well so you can return it if allowed and research into their return policy because you may get a DOA.
