Title: Just hit 5.5 PH, & on our way to 8.3 within the month
Post by: kryptk on April 29, 2019, 06:35:40 AM
Video is worth 10k words.

Moved 800 miles for cheap(er) power in 2016...killed it for a year and half.... then crypto-winter put us on a diet of rice and beans (black mostly).  We made it though and now...

Take 2.0.

when caviar ?  ::)

the video was not clear enough, no sound , but i love those green blinking lights, every time i see them i smell bitcoin , i assume most of those gears are S9s ?

it would be great if you could include more technical details regarding the set up and so.

Well done by the way, and good luck!

Would you tell us what pool are you using, and why?

I would guess via.btc.

Well good thing you snagged up some cheaper power and were going full board into 2017. Nice to hear you made it through Winter likely leaner and hungry for coins. I must admit it would be interesting to hear the plans for getting up to 8PH. Is that just from replacing older gear, expanding or a combination of both? I agree with mikeywith, more info and pics; I like seeing larger operations up and running.

Not sure if you shop around for pools often but your large enough you could qualify for some of the BTC giveaway on KanoPool (https://bitcointalk.org/index.php?topic=789369.0)

With 5.5 PH/s I would go solo... At the moment, this would produce about 3.5 BTC/week. Always depends on the costs of power, of course.

VERY bad idea. At 5.5PH your solo variance would be astronomical.

You firstly currently would average more than 60 days before you find a block (though the next diff change will be over 10% so it will be longer and include many more diff changes).

And if you hit over a 200% block (which is expected 1 in 7.4 blocks) that'll be more than a 1/3 of a year away, with no income until you find a block.

5.5PH is not big time - it's quite small compared to the bitcoin network which is currently over 47976PH.

Op has 10x my hash rate

A lot of smaller hash setups can afford to mine on with zero coins for months on end.

I have a sidehack r606 and 3 new pac sticks  they hash about 1.1th pointed solo most likely they never make money.

but I have 550-600th pointed at low variance pools.  they make money and allow me fool with some solo mining.

A 3 cent power guy with 100 s17's  hashes about 5500th he burns 220kwatts an hour or 158,400 watts a month at 3 cents = 4750 monthly

He should hit a block every 60 days  but to have a 180 day stretch can happen.  At one time a pool  did back to back 99% cdf blocks  this would be near a year without a block  more the 60k in power cost. with zero income.

The op could point a lucky miner say one of his 100 s17s at solo and point 99 at a low variance pool

No, he should average a block every 1 Diff of mining he does. That's the correct (and very different) expectation.

He could do way better or way worse. Current one Diff means he is not expected to find a block before more diff changes, so it somewhat could stretching out forever when you solo (or pool mine) that small.

I guess it just depends if he's a gambling addict or not if he goes with any solo mining. 1PH of current miners is around 20-30 miners (say 25) so 8PH is 200 miners so maybe $300k or more investment in miners. Addicts 'usually' don't have that sort of money to burn :).

I stand corrected. But as a gambling, it would work.

But why do you think the next diff change will be over 10%?? When I look at the trend: Shouldn't it go rather a bit down?

You can check out this thread Phil started. It's speculation about the network difficulty and has a pretty steady discussion around it: Well the 2018 btc diff jumps are over so what will 2019 bring us? (https://bitcointalk.org/index.php?topic=5091665.0)

I like the odd gamble and game of chance, but definitely not with those kind of numbers. It would be nice if OP comes back and talks with us a bit, wouldn't mind finding what they do and why.

I don't 'think' it will be over 10% - it's a simple calculation to show why it WILL be over 10%.

3-4 days of new miners pushed the diff up 5.5% - it was pretty static for the first 10-11 days after the previous diff change.

So to do that: 5.5% = 4/14 of the hash rate increase.
i.e. the hash  rate increase was 5.5 * 14 / 4 = 19%

However diff went up 5.5% already so that leaves another 13.5% on top of the previous diff to stabilise JUST to the hash rate at the end of the diff change that just happened.

13.5% on the old diff will be 12.8% at the new diff - so expect at least 12.8% at the end of this diff change if no miners are added during this diff change and no miners drop off during this diff change ... which of course total miners will go up this diff change also ... i.e. it should be at LEAST 12.8% for the next diff change.

If gambling always worked, I think they’d call it something else.

when caviar ?  ::)

That my friend is the exact question my women asks me nearly every week.

... the video was not clear enough, no sound , but i love those green blinking lights, every time i see them i smell bitcoin , i assume most of those gears are S9s ?

it would be great if you could include more technical details regarding the set up and so.

Well done by the way, and good luck!

I'll post more pictures / videos once I'm done (i.e. have time) with this marathon of construction, setup and configuration.  My days are mostly full of setting up systems, wiring, making deals, dealing with the state/county and crooked contractors...  I'll post more images in a couple weeks - give or take.  Everything you see is some version of an S9.  Some I've been running since 2016 in my initial data-center to a couple hundred that were new in the box.  Approx 130 miners & 8 more 60 amp iec309 receptacles to wire and I can take a breather.

If you have specific questions let me know.

I would guess via.btc.

Either that's a good guess or ?

But why do you think the next diff change will be over 10%?? When I look at the trend: Shouldn't it go rather a bit down?

... it would be interesting to hear the plans for getting up to 8PH. Is that just from replacing older gear, expanding or a combination of both? I agree with mikeywith, more info and pics; I like seeing larger operations up and running.

As I eluded to in replying to mikeywith it's new construction so getting to 8PH is -1 part finishing the electrical runs/receptacles and -1 part waiting on the last machines to arrive.  Plus a few parts working out the kinks in airflow, filters, machines & power supplies with the issues you can imaging from used equipment, etc.

We went with 100% used s9's (even the new ones were from miners that never made it into business due to county/city moratoriums - mostly - and had them sitting in storage units) - we picked them up when the market bottomed.  As one reply above suggested getting to 5-8PH with S15s would be a major financial undertaking.  I'm playing the numbers and the quickest way to 8 was used equipment, the quickest way to 16 is using the income from that used equipment to upgrade (which isn't actually the plan).
