So its official another 50k bites the dust.
Only four left.
8344  Economy / Speculation / Re: Wall Observer BTC/USD - Bitcoin price movement tracking & discussion on: November 02, 2021, 04:01:49 AM
sandwich 🥪 is made.

look for a major lift now that buddy has a sandwich 🥪 to curb his appetite.

buddy needs a sandwich 🥪 to do some heavy lifting
8346  Economy / Speculation / Re: Top 20 days for Bitcoin on: November 02, 2021, 01:26:19 AM
Well no posting as of yet. But we have 5 in the 50000-50999 range.

and in fact on will drop today and leave us with 4 numbers in the 50,000-50,999 range and 25 over 60k.

After today exactly 60 days left to tack on higher numbers and drop out lower 50-51 k range then 51-52 k range.

We could get to 85 at 60k or higher and only 15 in the 58-59k range.

Even if we do not crack 100 or even 90k a sideways move in the 60-70 range would be really amazing.

Looking for silver in 1 ,5 , 10 oz  sizes.

Can pay in

Btc
ltc
doge
paypal

any name pieces work

silvertown
sunshine
ampex
engelhard

I normally self escrow but any well known seller I will pay first if they want it that way.

I could use about 20 Oz

I am NJ based and want to pay very close to spot.

Which is about 25 an oz.

So maybe 260 for 10 oz.

Previous Retarget:   Yesterday at 9:58 PM  (+7.8520%)

We are back to June difficulty levels, the price was below 40k at that point, now it's 70% higher, this is still relatively very good for all miners, I believe the days of negative adjustments are over, hopefully, we keep getting only small spikes of 3-5% at most, we need 25% increase from here to hit the ATH level, I think we can hit that around 1-15 Jan 2022

Maybe or maybe we flatten out to 1,2,3 numbers.

which means feb or march for new high in diff.

That fan error must be corrected. No more complex than this.  The gear will never work with that fan reading at 30,000.

Now as I said the fan could be the issue.
the controller could be broken.
the firmware has an issue.

the most likely problem is the fan

you could load braiins on a sd card  and try to set it for 1 fan maybe it works which indicates a firmware issue.

I have repaired multiple s9's with this issue

a new fan and or an sdcard with braiins software usually fixes it.

some times it does not and a new controller its needed.

lastly all three may not work and the boards are dead.

It is kind of strange that we are staying quite high in the bitcoin history of price locations.. largely staying in the top 20 since about 10/15 with the exception of 10/27.... and hardly any fanfare..

Of course, these remain exciting times. .while many of us do have senses that higher numbers are going to push the top of the chart.. hopefully?  Hopefully.. the rest of the year.. maybe into next year would be nice, too... .

It is likely going to take a while to push all the pre-mid April 2021 numbers (or would we say dates) towards the bottom of the chart and off of the chart.. which hopefully does happen in this cycle..... first, second or third quarter of 2022.. though there are quite a few pundits who consider that the end of this cycle will come this calendar year, which could make it more difficult to push some of the earlier 2021 numbers/dates off of the top 100 chart.

My gut tells me it is the last play for big mining/asic builders.

They keep it like this due to chip shortages.  This will pass soon but I am thinking 2022 Sept-Nov. will be the end of the super cycle.

But what do I know.  Not much.

Still stacking AND HOPING YOU are more correct then I am.

Too many bearish posts here today, that should be a massive green candle, soon.

I doubt it.

As I’ve stressed recently, the top is in & it was a very mediocre one in all honesty, only just over 3 x the previous cycles high. I predict $60,000 will fail to hold in the next days & then a new bear market will be confirmed.

I say this as a friend to all, dump your bags & buy back at $10,000 in early 2023. The top is in, nobody wants to buy bitcoin at this price. Retail investors drive bull markets & all they want to buy is dog meme coins. Turn the lights off & leave the office guys. This party is over for a few years.

$60,000 a distant memory by this time next week & the start of a long, cold crypto winter.

Sell everything.

spoken like a true wannabe a-hole and or POS

but like a-holes we all have them and we are entitled to write posts in that manner.

70k by Nov 5 once USA election results are in and the left gets hurt then BTC will have a bigly rally.


"There will also be at least four special elections for the U.S. House that not only could affect Democrats’ narrow eight-seat majority but also give us an early clue as to the political environment in 2022."

quote is from here :

https://fivethirtyeight.com/features/all-the-elections-to-watch-in-2021/

if all four seats go to the right the house is pretty much deadlocked and biden agenda will be halted.

This is over 10eh if my math is right

so 10 s19 = 1ph

100 s19 = 10ph

1000 s19 = 100ph

10000 s19 = 1eh

10,000 s19 = 10eh

A lot of gear.

A bullish number.

Im a new member to Bitcoin Forum,

Here's an article to read:  https://www.engineeredfluids.com/post/corrosive-sulfur-in-mineral-oil-a-killer-app-for-electronics

Its an interesting subject on cooling but its not without questions, one issue on corrosion may lead to increase  operational costs.

Then theres' this article: https://www.engineeredfluids.com/for-crypto-currency



This looks better than the beeminer as you simply run coolant tank to a radiator and do not need a water based system to cool the coolant system

Yeah, bad choice of words on my part. I was just pointing out (poorly) that sidehack was not the only one that TTBit ripped off.

Drifting a bit here, but it does make you wonder how much counterfeit stuff is out there they we don't know about.
If someone make a stick like sidehacks or any of the others but instead of customizing it made an exact clone how many could they sell at close to full price.

8357  Bitcoin / Mining support / Re: 240v Garage Setup Electrical Help on: October 31, 2021, 02:59:01 PM
If you have an electrician friend just let them get all the equipment for you. Be plain about what the end result should be, “I want 10, 30A 240V circuits with receptacles or junction boxes to connect these ten miners.” They should be able to get the right parts for you and often from a distributor with competitive pricing.

A few things with residential services. The power company won’t hook up a 200A panel to 100A service so be sure you can get 200A service before you buy a big panel board. I would also get a physically larger panel too, that way you can install the breakers with a space between them (for cooling) or have room for extra breakers for future.

Quick electrical lesson: breakers are there to protect the wire and not the load. The size of the load (your miner, approx 3000W) dictates the size of the wire (3000W/240V=12.5A, adjust for continuous running; 12.5A/0.8=15.6A so 12 gauge wire minimum) which then directs the size of breaker (12 gauge ampacity is 20A so 20A breaker).

The voltage references can seem a bit confusing. Standard system voltages in North America have some variance. Single phase residential is often 220-240V. I think it also goes back to older electrical standards. Things rated a few decades ago reference 220V or 230V a lot. Most newer standards reference 240V. Long story short is that your power at your place will be in this range, leaning closer to 240V likely. Your power company might be able to adjust your voltage up or down a bit at the transformer using winding taps if you are finding it too low (less than 220V).

Pro tip: you can avoid the cost of larger receptacles by direct splicing the miner cables to the circuit wires. Just cut off the male end, strip back the cable a bit, use a tester to find the ground and power carrying wires in the cable and splice it all in a junction box. It’s more work overall and the cables become fixed to one location but this can save a bit of money. Your electrician friend will be able to help get this right. And definitely get it right because weird things can happen if some wires are accidentally crossed.

PDU is probably not required. They can add value though if you get one with power monitoring and smart switching. If you don’t want to go with a receptacle per miner route or use junction boxes to hook the miners up a PDU is a nice prebuilt way of splitting larger power up to multiple devices. A 30A 240V PDU is only going to be able to power a couple miners though so the added cost might not be worth the benefit if you have to buy a bunch of PDUs.

the cheapest 30a 240v pdu  used is this:

https://www.ebay.com/itm/143399400162?

the plug is l6-30p  it has 4 breakers for the 4 c19/c20 jacks and a main breaker

it can do 2 s17 on low setting
it can do 2 s17 on normal setting
it can not do 2 s17 on turbo setting

if you buy them look for these wires to run to the s17 psu

https://www.ebay.com/itm/184114573116?


we went away from this setting due to our power having long brown out dips to 188-195 volts. when this happens the pdu would trip

but it is viable way to run s17 gear or even s19 gear

s19 will be 1 unit per pdu.
8358  Bitcoin / Mining / Re: Immersion cooling - Beeminer hive - water consumption on: October 31, 2021, 01:11:25 PM
very interesting piece of equipment.

https://beeminergroup.com/en/catalog/beeminer-hive-12rx/



They mention a closed water circuit can be used. But you are in a desert so using a pond is not an option.

Neither would using a swimming pool as I think the water in the pool would get too hot.

Now if you dump the coolant heat into a closed water system with lots of truck radiators and fans maybe it works.


https://www.ebay.com/itm/403085000869?


so beeminer with immersion liquid exchanges the heat into multiple truck radiators. the truck radiators need shade from sun and tons of fans

you need to stay under 50c. and what is the desert max temp?  (120°F − 32) × 5/9 = 48.889°C
So you could have an issue due to the suns heat. I also know  my estimate of max temp could be off by 2 or 3 °C

BTW savetherainforest main point is BTC will fail one day.

he is spot on, but the point of failure will likely be more than 50 to 100 years from now.

most pow coins will fail as cryptology will likely fail with the invention of some new math.
