So I'm really new but I'm looking at let's say antminer S3 okay and then let's say a teraminer like an S2 (OR ANY TERAMINER)
Would or should I save my money for a teraminer ($1300-$1800)
So no here is the thing. S3 is about half a bitcoins and your required to buy in pairs so 1bitcoin for 2(I'm rounding down) so at this day about $500-$540 for 2 S3
so
456*2=912gh for 2s3
1tera=1000gh


It seems cheaper to buy the 2s3 (maybe more ) as to the teraminer right?

Or is my math wrong?
