Does anyone have any info on the life span of Antminer S7 Batch 8 or Batch 9? Or at least approximately About 3 days from now, it will not survive the +20% increase in difficulty. With the help of a $460 BTC it will survive this increase without problems, short term is not the issue.... Rich

Lifespan in terms of making money or reliability? I am asking because this is going to be my first miner ever. I am planning on running it 24/7 in a really cold room. Noise is not a problem. Electricity is $0.089 kW/h. In my country the average monthly payment for a job is $220... With my calculations this machine is going to be bringing me around $415 per month and around $330 profit. Break even in 3 months .

With the difficulty rise, you will make 400, then, 350, then 300 per month (im pulling numbers out of thin air), etc. But you will make a profit even after halving hopefully, you electricity isnt too bad. Also consider that you will sell the miner after a while. How much will it be worth after the halving ? Hard to say. Judging from experience, it will retain much of its value. Its a lot of money (even though some people here dont hesitate to drop 50k on miners...but then again its all re-invested money). Also dont forget customs and taxes, I had to pay over 300$cad (god damn...).

Customs are not a problem ![Smiley](https://bitcointalk.org/Smileys/default/smiley.gif) Since I got into bitcoin like a month ago I still do not know how easy/hard it is to sell a bitcoin. I created a wallet a few days ago and bought $20 worth of BTC just to see how the procedure works. Now I want to ask, if the difficulty rises, isnt the BTC's price going to go up? And literally less than 100 people in my country know about BTC and mining.. Not sure how I am going to sell the miner. And I was asking about the life span meaning how long till it dies after running 24/7. English is not my native.

Well in my experience miners run a very long time, 24/7. Some people have problems, but it seems to be hit or miss. I've run mine (s1 to s5) for more than a year no problems. Macedonia eh? Cool, I've been there once...road trip...nice place, I remember eating at a 5 star restaurant next to a lake, for a couple of bucks...awesome country. The price doesnt go up with difficulty, but right now it is. Buying mining equipment is a bit of a gamble, like buying bitcoin I suppose.

So do you think the bitcoin will rise in the next couple of months?

You've probably been to Ohrid. It's where I live. So do you think the bitcoin will rise in the next couple of months? Yeah I believe we are going into another massive pump...to be followed by a massive dump ![Smiley](https://bitcointalk.org/Smileys/default/smiley.gif)

Spec wise it's the same. Price is reduced, delivery is later. Rich

But thats a "pre-order" for one month...a lot can happen in one month.

This document has been shared for anyone to use.

So as they said on Batch 8 this looks to be the Final Spec and we have exchanged Spec Changes at every batch for Price Reductions at every Batch. ![Smiley](https://bitcointalk.org/Smileys/default/smiley.gif) Has anyone got any more info / pictures of the controller board, with reduced number of Fan & Hash connectors that was reported?

Interesting re B1 S7. It suddenly went from 4.79 Th to 3.65 Th for few hours (before I noticed) without any zeroes or temperature extremes. Soft reboot fixed the problem. two possibilities: some chips dropped out, but somehow boards did not show it or miner "got tired' and "decided" to take it easy ![Smiley](https://bitcointalk.org/Smileys/default/smiley.gif) This is one of the earliest B1 machines ever delivered (on day two of B1 delivery-9/24 or so)-hashing close to 3 months already, so it would be interesting if someone else observed the same.

This makes things more difficult and leaves little options in the future if things should go wrong. I understand all of the components used for each unit adds up with multiple units and getting rid of components reduces manufacturing cost but geeeeeeeez.
