Additionally, if you are talking about Scrypt or other alt coin mining please move this out of Bitcoin mining speculation.
Shall I take it as ,,, THERE IS NO PROFIT WITH BITCOIN MINING ?
If i can make 2 or 4$ a day, with mining as profit, that will be great .
How much does your power cost per kwatt?
8 cents a kwatt means you have a chance to profit.
Bitcoin miners are very loud.
The Avalon 741 is about 800 usd. Add a rasp pi and a psu it is near 1000 it make 8 or 9 a day.
Good luck buying it.
I built 3 rasp pi 3s I can build one for about 60 it is better then the one they sell for 100. i use a 16gb card they use a 8 gb card.
so
794 avalon 741
60 rasp pi 3
90 1200 watt psu that runs 1 you need 240 volt power to run at top speed but you can run at -2 with 120 volt power
944 total cost
if you do 2
1588
60
119 2400 watt psu that runs 2 only uses 208-240 volt power
1767 for 2
If you can give me rough idea i can also replicate the same setup ( if its profitable )
