I recommend S3.
Electricity costs depends on where you live.
why s3 ? more powerful s5.
i interested me i that install 30 miner in one house after some don't burn ? enough power wants 30 miners
It depends on your electricity price. If very low a S3 is better for some. Most the S5 is better with its more efficient chips.
And go slow.... I highly doubt your house can handle 30 miners. It's summer and heat with 30 miners will be hard to deal with. Not to mention setup costs.
Did you contact Bitmain on your first miner and get it running properly yet?
yes i have very low cost electry 1KW- 0.05$ this means that s5 can't withstand .
than i will buy s3 .
you why think that my house can't handle 30 miner ?
If I remember right you live in a hot area. 30 miners create a lot of heat. You will need ventilation, electricity wiring, etc, etc.
With amount of trouble with a single miner I just don't think 30 would be a good jump. I think you might possibly be trolling.
Most of all interested me what electricity wiring should ? probably good copper wires is need ?
don't will damages 30 miner electricity?
heat isn't probllem.
Heat will be....
But is 15 TH the goal of hash? 30 S3 + give or take is 15 TH
If you got S4+'s you are talking about 6 units instead of 3 units. So if you were serious that would be route i would go personally.
And it looks spammy on some of your post's. I HIGHLY suggest taking bitmain up on talking to their support team, with native speakers. Or trying a local board. There is just a language barrier that seems to make post look spammy or answers not going across.
