Hi,
I have 30k to invest, so i think to build a mining farm.
I selected this hardware :
- ANTMINER S7 * 25 -> 22401 USD
- APW3-12-1600-B2 * 25 -> 3500 USD
Since kWh is a bit high in my country (0.16$), i found that miner hosting can be a good idea. I found 3 interesting offer :
-
http://zoomhash.com -> 0.08$
-
https://cryptominer.ca -> 0.09$
-
http://bitcoinasichosting.com -> 0.11$
Then i decided to use different bitcoin calculator to see the "possible" profitability, using the shippest hosting provider (zoomhash)

coinwarz don't take difficulty increment into account, so i assume the result is almost false.
On tradeblock and 20% difficulty increment, it's not rentable. With 7%, i can use the bitcoin earned + selling the x25 rig to built a new farm with more rig (and repeat the process regulary, adding more and more rig, x25, x35, x50 etc...).
On bitcoinwisdom it's not rentable even with 7% or 20% difficulty increment.
I know bitcoin mining is very difficult and there is a lot of factor involved (ive readed a lot of topic in this section), but it's appear that even with starting a new build rig with 30k and a low kWh price the profit seem impossible, or you need to be very lucky.
What do you think ? Invest or not ? Take into account that i have money, so if i lose 30k it's not the end of the world.
No, 0.08 is too high. It would be high risk.
And tradeblock is asking you how much diff you think it will go up by per month, thats why its different from bitcoinwisdom which ask you what do you think the increment per round will be.
Bitcoinwisdom at 7% is a fair guess at how bad your profit looks, which is very bad. Get a better price on the electricity, or hardware or something. Maybe look whats the hosting cost at hashnest.
If not, things are looking a bit icky with the bitfury stuff and private farms getting super big.
