Topic: My "mini" mining farms , set up + wiring (Read 4704 times)

Keep in mind that almost 99% of miners consider the fiat profit as oppose of anything else, based on that, your statement may very well be inaccurate,notice how that as for right now,even mining with an old gear like S7 which is built on 28nm is in fact still profitable for 5 cents per kwh.

coin price is the number 1 decision maker in everything mining related, if after the halving and assuming difficulty increases by double, it only make sense that most 16nm gears will be paper weight but what if BTC price is 50k by then ?

an S9 today makes about 5$ per day

after the halving (without taking price into calculation) S9 will make 2.5$

assuming diff will double s9 will make 1.25$ per day.

if price was to stay at 11,000$ per coin, that would be valid, but if say BTC is at 50,000$ after the halving then S9 will make 5.6$ which is even a better profit than before the halving.

indeed non of the above is guaranteed to happen, but non of it is far from possible, diff doubling is very doable, coin price at 50k is very doable too.

The great thing about mining is that diff takes a lot of time to double, while price really takes no time when it wants to double, hint in 6 months we went from 3k to 14k  = 328% increase to be accurate, while diff went from 5.6 to about 8 which is not even 100%.

I agree with you, i think there is a chance for at least one major downtrend before the halving, then i guess another after halving and some calming afterwards (before the usual). People need to pay attention also to manufacturer delivery of the newer more efficient units, which impact the diff and lower the income of those still using older units, which can probably still be squeezed a bit more juice from until the halving...

Post halving i don't think there will be much interest for 16nm units anymore, now would be a good time to sell/replace those, while some people still want them to squeeze them before the halving.

I do tend to agree to this, not because I did the exact thing, simply because of the numbers, since this is a bit of topic because this thread is not related to investment but solely focus on wiring and set-up - I decided to start a new thread to discuss your statement here > https://bitcointalksearch.org/topic/m.51705339

Would be great if you could join the discussion.

Time for aggressive expansion is when pricing is low to lowest. Which I feel will be coming to a close here by Q4. Otherwise it's simply adding hash to stay ahead of diff and finding better efficiencies with what you have to drive revenue.

When in good times, plan for the bad times. Then you can always have a future. Plan ahead so you don't get caught off guard. Some people go greedy and start spending all their income in expansion, not thinking the situation might suddenly reverse, as it has done several times in the past.

I'd say you made a good choice overall, nothing wrong with spreading it out a little in case we weren't in such a great situation right now, if only we could see the future. Good on you for not giving in to the temptation, it's tough when everything on paper says do it. Not going to lie, when you were talking about this I almost hit you up with a proposal to buy/host with you - essentially try and insert myself into your plan if you had space. Then I took a breath remembered I had just upgraded everything mining at the house and held off on asking. Finally starting to rebuild some of the reserves, which feels nice especially at these prices.

If you get a chance ever you should throw up a few pics of the "Gold Rush" setup.  - Get in and grab what you can fast.

I always forget about the Bot, and now realize why I couldn't find your thread - it moved.

sorry bud i just saw this, if you mentioned my full username i would have been notified by piggy's bot  .

okay what i did was actually reduce both risk and reward , i had to pay a lot more per miner (of course this includes other expenses )since the numbers i had in mind required a certain amount of gears, so i went in with like 40% instead of 100% , ROI got extended by about 1.2 months based on the initial plan, but with the price rising i am still aiming for about 3 months ( or just a bit more )

i can't say i regret not going all in, , because the btc hodling increased too (dollar wise) , to be honest i am too lazy to do some the math that would suggest if my decision was the best or not , but i am happy with the fact that for once i could resist the temptation of going balls deep into mining.

Mikey, I've been meaning to ask. Did you ever go all in on Mining gear and expand the farm with that cheap power deal? Or did you go the other route and amass coins?

Trying to catch up with a few people who were thinking along the same lines to see who decided on what.

True, a bit of heat is good , another reason is the that apw's wires are not long and flexible enough to allow you to easily eliminate the heat comes from psu, it is doable , but not easy at all.

I have seen many people simply let the exhaust of the PSU go inside the miner, that extra warm even helps lower humidity a little.

I don't , they don't produce enough heat for me to worry about. as long as the heat that comes from the miners is taken care of, psus should not be on the list of problems.

I still don't see how you are venting the PSU's

This is how i do it anyway, look closely at the pics.

just one question bumped into my mind ,about your miners you have separated cold and hot room , some how your miners are still in the hot room their body will get hot , what about putting them in the cold side and just let the blower fan blow out the hot air to hot room  in this case the miners wouldn't be cooler ?

moisture is bad for almost everything , but with swamp coolers you save on power , also you mentioned that it's not humid in your region, then swamp coolers should work great for you, but then you need to watch the level of humidity.

i am not an expert in this field, most of my past experience is trial and error, i hope someone who has more experience will provide you with a better answer, tho i doubt that the information you provided will be enough for a perfect advice.

hello , but the swamp coolers make it very very humid , dont u think that it will shorten the server life ?
i want to build a farm and it is possible for me to use swamp coolers and it is not humid in my region but again Im afraid that moisture will harm my servers

It looks like a great setup; How are you venting the PSU's? I am doing something similar but not isolating the Hot side because fo the PSU's, simply relying on the air flow.

I would have something like for a client " paid job" , i do some dope network wiring when i am going to get paid  .. but when i do something for myself i always focus on getting it to work and don't really give much weight to how it looks.

Hey mikeywith,

Are you planning one day to make a wire perfectionism ? Something like that. This will definitely cause some orgasmic feelings on this forum part
