How many bitcoins can be mined with Spondoolies-Tech SP35?
 

If you were to invest about $100K (so about 28x SP35), what would returns approximately be in the mining effort?
Are there better ASIC based options out there vs the Spondoolies-Tech gear?

If the SP35 can do 5.5TH/s then if I get 50 of them @ $175K investment, I should be able to generate approx. $37K/month in revenue @ current exchange of $350USD/1BTC.

Get them powered up for $.05/kWh~ = ~$5500/month in electric cost

Hmmmmmmmmm.............. then hold as many until BTC rate goes up again to $500? $600? Really make bank then too.

You sound smart... My answer is.....green.

The hostory of these hardware buys is pretty consistent.

1 - never ships
2 - hardware is crap
3 - you get it late and the diffiiculty has priced you out of the system as ne hardware is kicking ass.

I can get 50x SP35 units delivered by end of November to Iceland :)

The mining difficulty will go up before you recover the initial investment. That means your monthly total btc mined will go down over time.

If you are counting on bitcoin rising in value as part of your profit strategy it might be better to just buy btc and hold.

Yeah why not just buy 100k of bitcoin and save on electricity?
