what advise me . ?
Don't do it, it s worthless. You are going to waste your money.
can you really tell me why do you think like this or may be you have lot of experience in mining with antminer s1,s2,s3....
so i am serious to buy it so it will be better for me that you confirm first why it will be worthless for me?
Why did you dig up a one year old post?
I will believe you on the question .
A s-1 at best uses 1.2 watts when clock low and under voted.
An s-2 uses around .9 watts
The s-3 uses about .6 watts when clocked low and undervalued.
These watt uses are very high. So they would lose money .
