Time to do a little math.
All this assumes that you can install hardware today.
Network Thash/s Today 6,357,467
Blocks per Hour Today 6.94
Bitcoins per Block 12.5
Bitcoin Value Estimate 2824
Calculated Information as of TODAY
rewards / day 166.56
BTC Reward/Ghash/S/Day 3.27489E-07
If you can install 110 TH/s, you'll earn:
BTC Reward/Day 0.035015116
Estimated Earning/Day USD 98.88268718
That's 8 Antminers, which would consume 12,000 watts. You'll burn 12KWh per hour. 288 per day. 8640 KWh per month.
If you have to wait until September, you'll need somewhere between 10 and 14 of them.
Note that none of this math accounts for cooling. 12,000 watts makes a lot of heat.
Good luck with your empty house.
10 s9's will net you about 130ths at nearly 11 thousand usd, thats just for the machines. the issue with cooling could be off set if you live near the empty house and vent the air to heat your own house. otherwise you'll need some industrial grade fans. just off the top of my head id say you would need to invest at least 20k usd for everything. if i was you i would go for it, provided you do the maths with exact figures
