I'm adding to my hardware. Is $80 for 110 Gh/s worth the cost? Whatcha guys think?
Watts?
and Power costs per kWH?
If watts were 200 watts at the wall and power costs are .15 per kWH
@ 39 Billion difficulty & $332.00 per BTC:
Power costs for 1 month = $21.92
Revenue for 1 month @ $332.00 for BTC = $13.81
Less Power Costs for 1 month =
minus (-) $8.11 [A LOSS]Depends on your watts and power costs...
An S1 at 180 Gh/s with BTC at $332.00 and 350 watts at the wall with 39 Billion difficulty and power costs @ 0.15 kWH:
Power costs for 1 month = $38.35
Revenue for 1 month = $22.56
Less Power Costs for 1 month = minus (-) $15.79 [A LOSS]An S3 at 450 Gh/s with BTC at $332.00 and 375 watts at the wall with 39 Billion difficulty and power costs @ 0.15 kWH:
Power costs for 1 month = $41.09 (.15 per kWH)
Revenue for 1 month = $56.39
Less Power Costs for 1 month =
$15.30 [A GAIN w/power costs @ .15 per kWH]Power costs for 1 month = $21.92 (.08 per kWH)
Revenue for 1 month = $56.39
Less Power Costs for 1 month =
$34.38 [A GAIN w/power costs @ .08 per kWH]With BTC price so low at the moment in relation to difficulty, one's power costs and watts at the wall in relation to hash rate is VERY important to KNOW if it's worth it or not.
My power costs are .08 during the winter in Alabama. So, that helps a lot for me to go with a difficulty that is quite high with S3's. It would be much harder for those who have much higher energy costs.
Using an older rig that uses more watts than hashing power (200 watts for 110 Gh/s) is not good in this high difficulty environment and BTC at a low dollar value. If it uses 300 watts for 110 Gh/s, that is even worse.
