Topic: Bitmain's Released Antminer S9, World's First 16nm Miner Ready to Order - page 285. (Read 531298 times)

Summer mining is not that bad it just takes finding out what you need in your area.  It is very location based as there are multiple way's for cooling, and different climates have best way's for them.

I sadly am not in a place where evaporation cooling works in my weather.  So I use lot's of CFM's of fan's in my mining area it took last summer to fine tune it in but this summer was easy with it all in place.   So really just takes once on setting up for summer.  And it depends on how many watt's of miners your running on how much heat you have to deal with.

If not a lot of miners much easier.  I have two big fan's and a professional gable fan that do good for my mining area.   Again goes back to fine tuning I had to get a professional gable fan as regular house one's were just not exhausting enough heat for amount of miners I run sometimes.  Here is my journey to find a good way to cool my miners - https://bitcointalksearch.org/topic/summer-mining-fansother-summer-equipment-1020826

Awesome setup Erumara!!!

THANKS for the IDEA!!!

Yeah -- it is EASY in the winter -- summer is when it is tough.

But, unlike those number crunchers who doom and gloom each and EVERY year -- I am just THRILLED to get the latest and greatest miners added to my hobby.  I've been mining since 2011, and although I've lost a lot of coin to Gox, Cloud Mining scam, blockchain, and others (not to be mentioned), I'm STILL way ahead.

It is a VERY PROFITABLE hobby -- unlike MOST hobbies.

If I lose THIS YEAR -- I'm STILL way ahead!!!

That is the way I look at it...

 

We actually had the venting changed in our house, with the heat from my bitcoin room in the basement being pumped into the air return of the first floor furnace and being directed into the sun-room above the bitcoin room.  Very nice in the winter, we actually had windows open almost all winter long (and we are in the mid-west, with winters around 32F and often below).  So either free heat and paid electricity for bitcoins, or expensive electrical resistance based heat and free electricity for bitcoins... lol.  Its once of the reasons I find calculating ROI tough.

Rare indeed, it's taken 4 months of running these miners before the wife even started to warm to the idea.
Of course it didn't help I had to tear open walls in the recently renovated basement to do so, but so far the tongue-lashing has been worth it.

Edit: Adding picture of "grounds for divorce" as she put it.

I've actually found myself at a different mental spot, probably delusional:  So long as my miners can produce enough BTC to buy the next round of technology (based on power consumption levels), and produces enough excess that I can cover the power used to do the first part, I'm happy.  If that excess allows me to buy a few things along the way with BTC, all the better.  So far, that has been the case for me.   Purse.io provides a convenient Amazon vector, NewEgg takes BTC directly, and so does Gary Johnson for President - good enough for me.  I do that with a power budget is about 9KW/hour, enough to roughly run (6) S7s and/or S9s plus a bit of older scrypt gear.

I judge my success when new technologies appear, so did so when the S7 came out, and again when the S9 came out.  This is a hobby for me, and my BTC balance is influenced by other things, like surprise profits on alt coins I created 2 years ago, but that is all part of the hobby.   e.g.  I've "wasted" a ton of money on techs that never paid out (remember Antminer U1s and GridSeeds?), won fantastically on others, and have some that only time will tell.  However, overall, both me and my spouse (who helps on the spending side) are happy.  In fact, my spouse encouraged my recent S9 B5 purchase, which I suspect is reasonably rare.

If I pay 3 BTC for the miner, the electricity cost doesn't change the original calculation.  Whatever percentage of the earnings has to be sold off along the way for fiat in order to pay for electricity doesn't change the fact that I still need to earn 3 BTC from the miner to ROI in the long term.  BTC to fiat exchange rates can complicate how much BTC has to be sold off along the way, but the long term amount of BTC that has to be accumulated remains the same. 

Otherwise we are back to another conversation that has been rehashed in this thread repeatedly which is the "buy BTC and hold" or "buy the miner" conversation.

My point is just that when someone posts some version of "these will never mine the BTC they cost, why are people buying them?" and then someone else posts about how buying the miner is gambling on BTC going up, they are having two different conversations.  Which is exactly what happened in the posts preceding this.

This sounds good and make a great deal of sense. The only flaw in the "BTC only" logic is that almost nobody has predictable operating costs (i.e. Electricty) that is priced in BTC. Hence for virtually everybody, the price of BTC impacts their profitability computations, even if you only care to use BTC as your metric.

But some of us already have BTC that we mined.  You buy these things in BTC so it makes sense to consider ROI in BTC.  If you guys are talking about buying BTC with dollars and then trying to ROI in dollars that is not the same conversation that other people are having here.

Except that we don't live in a static world.

Difficulty will decrease, price will rise, etc.

I've never regretted buying in early in the past, and expect this year to be no different.

Is investing in "penny stocks" a hobby?  Don't think so.  Mentality is likely similar.  Nobody is buying with a ROI hope at Today's prices, they are hoping the price rises.  You don't buy a $5 stock hoping it goes to $6, you hope it goes to $50.  Same thing here.

Yes, with BTC, there is the alternative of just buying the coin itself, but that is not nearly as much fun.  Its a paper transaction vs. having something you can see (and hear!).

I do not understand either. I have tried to picture multiple scenarios but none of them makes buying an S9 the wise move at these prices. They literally need to cut the price of the next batch in 1/2 for it to be at all even possible to imagine breaking even. Seeing how happy people are to be parted with their BTC in this thread it is apparent that mining is becoming a hobby and a form of nerd entertainment. It definitely is not profitable or even potentially profitable for anyone investing BTC at these prices.

LOL BTC3.2 for something that will never mine half that.

If you had %100 free electricity you could never ever ever come close to breaking even on this.

I see batches B6 and B7 are up for sale... And no decrease in price with halving 2 days away...

I think we have already seen our run up in BTC price from Sept to now from $230ish to $600ish.  Which is good money at the current reward rate on the S9, but after halving at these prices it will mean grinding it out.  ROI? I don't see any of these later batches ROI anytime soon since you didn't get the benefit of the bigger reward to recoup some of your investment.  Those that jumped on the B1 and B3 have the best shot of ROI and making some money.  The rest... Oh boy.  

If they don't drop the price there is no way the math works unless I am completely wrong about BTC price.  I guess anything is possible.    I will keep watching and see if the price of the S9 comes down to where it is realistic to think ROI in less than a year.  Just hoping maybe?  

Batch1 was 2400 USD + shippimg

I also always bump up my transaction fee.  On my recent order, I did so until the slider indicated the transaction was likely to confirm in 3 blocks.

They are built the same, and I felt that prospective buyers should be aware.  That is why I started a separate thread on the matter, and am only answering questions regarding the situation on this thread.


You know what they say, when logic and reason fail it's best to resort to name-calling.

Yes.. By crazy I mean't it makes no sense for the buyer.
For Bitmain those prices of course bring a big profit.

Heck, my B2 was ~2050USD incl. shipping

And now with S9 they have stopped giving coupons for loyal customers.

On the occasion when my transaction did not confirm for two weeks it had disappeared at one point from both blockchain.info and blocktrail.com only to reappear a couple days later.  I thought it had dropped off and I was going to give it a couple more days and then resend it but the transaction was apparently rebroadcast by someone because it reappeared on both of those block explorers and then was picked up in a block soon after.

But you're right Philip, we don't really know if that is the issue without the txid.  But based on what bitmain told him I am guessing that is the issue.

@not.you  he did not post the transaction id so I don't know if it is a double spend or a low fee.

 he is new and paranoid  he with holds the info needed to help him. He could be  a liar and a troll , but most likely he is afraid that revealing the tx id will hurt him.
while in reality it should have been posted in his first post.



@ op  try reading this and looking at the screen shot this is one of many things that could be wrong.
No one can help you with out the tx id.  so post it and also take a screenshot of it like the one below  in case it falls off the system.

https://bitcointalksearch.org/topic/can-anybody-help-me-to-confirm-my-transactions-1541249

 read here  and ask questions here  since you don't want to show the tx id


I do suggest you have screen shots of it in case it drops off the system.


this is not good enough

here is one of many possible things wrong

I can tell you this it is your money but you need to have the tx id and a good screenshot posted

some problems  can drop the tx id off the system.

I think all you can do is wait for the transaction to get picked up in a block.  This is why I always include an over-size fee when buying a miner from bitmain, to make sure it gets confirmed quickly.  I have waited nearly two weeks in the past for a transaction to get picked up that had too small of a fee on it.  In that case I actually thought it wasn't ever going to happen but it eventually did.
