I should will buy 50 s3 and this dont is problem .
I want just know , exist any cause that mining will shut down ? I dont want that my 50 s3 Dont need .
How many about years will exist mining ? My in house that will have miners
It will use around 16, 800W of power. Depending on where you live this could still be a problem. Houses usually don't have industrial level electricity.
For that power you will get 22, 500 GHash (±5%). That's 22.5 TH/s.
To get 22.5 TH/s you would need to buy 5 BF4500 miners. They would spend 15 000W of power. This should be better actually.
If you were to go for efficiency the Antminer S4 should be the best (I think).
The last Bitcoin will be mined in 2140 (could be a bit sooner). Mining won't shut down; the network can't operate without it. However there are different scenarios to consider: Bitcoin could die, your miner could become obsolete, the price could go down even further.
I going to will make fine electrisy wire and should will make electrisity3 faze .
