what happened to the 12ph that where on tron?
what happened to antpool, is it back to full speed?

so y the -4%?

inefficient farms for btc but ok for pumped shit coins?.....

Also most mining is Northern Hemisphere and the heat is coming.

For me summer rates jump from 13 to 16.9 cents. Add in heat factor my winter rates are 10 cents and my summer rates are 18 cents.

For others worse then above.  Now I sold off 12 sp20s and 2 s-5's  .  I kept the 2 avalon 4.1's .  I clocked them down to 1600 gh vs 2200gh as I don't need the heat they make.

I suspect a lot of miners are starting to down clock.  So a home miner may have a 20% drop off.  Since we are not the big amount of network hash rate our 20% drop turns into 3 or 4 or 5 %

Yep. I had to down clock my S5s to the default 350.

11th downclocked to ~10th
sp20 and sp10! the last one not so much but sp20 is reaching 120C per more than half of asics at ~25C ambient temps
s3+ and c1 have no problems with higher temps. sadly they need to go as i want one miner edge or 2...

so you may have dropped from 1300gh to 1150 gh say 10 or 11%   x tenthousand others just like you and that is 15ph .  Yes the southern hemisphere adds some as it is cooling say 3 -5ph a net drop of 10 or 12 ph

and you are right at our current -4%.  we are now at -3.70%

I went back up to 400 with mine for today as it has cooled off sufficiently to keep miners running under 50C. How hot do you allow the rigs to get before dialing them back?

The s-5s are really sturdy  what are your error numbers? As in under 1.0 percent  is okay. under 0.100 percent is good.  under 0.02 is really good.

 So if you are really close to 1% errors  back off the freq.

 as for temps I  suggest
 under 60c as very safe.
 60c to 65c as so so .
 65c to 70c as pushing 
 over 70c for 24/7/365 as foolhardy

The auto shut off is 80c but there are reports of it failing to work. So I would not run in the 70+ range.

Any drop is always welcome.
Glad that mysterious 50PH.s went and stayed in hiding...

you and me both.

with 103 blocks to go we are at -3.40%

https://bitcoinwisdom.com/bitcoin/difficulty

price is 222 usd

so about 12 noon on Sunday eastern standard time we will know what the adjustment is.

I am very interested to see the upcoming number around may 2nd or 3rd.  I wonder if we drop -5% with the upcoming warmer weather. WE need a price thread but that is really hard to guess.

Phillip,

it's seems like you feel duty bound to always take the -1.11% change guess, based on some previous exchange with another member. I would be happy to have that assigned to me, so you are free to choose what you might actually want. Feel free to do that if you want, and I won't complain or request a change later.

Thanks for organizing these, and also suchmoon for his generous .1BTC payout.

Thanks for that offer. I will mull it over.

With  86 to go.  So to turn positive we need to make the 86 blocks in about 1 hour.

If we make them in 15 hours we will be just past -4%

If we could get -4 that would get rid of a lot of the previous difficulty change of 5.84.  I am still amazed each time we get a negative. 

Deferentially a lot different then last April.  We were getting a lot of double digits last year.  Big change, but I guess price also big change from last year.

And gear stopped improving power wise

the s-3  was the piece of gear that altered the diff jumps.  then the very small improvement with the s-5 set the change more.

Mining has so become a power cost game.  Basically most all of Europe is forced out.  Once my summer rates start i will mine at a 2th 1000 watt rate.

And lose money or if lucky break even.

Heads up - I'm traveling this weekend so please give me until sometime Monday to pay out the reward. The winner please feel free to send your BTC address once the diff adjustment happens, and I'll transfer the reward as soon as I get back.

Regarding rules for the next period: it was suggested to not allow to change the guess. I'll defer the decision to Philip, since he's the one maintaining the list most of the time. So Philip if you want to put that restriction in place please let everyone know in the new thread.

Seems we're heading for a nice drop now. Anyone owning last-gen hardware like the S5 should be in good shape for a few more months.

[alh]

I am curious about reference to "last gen" as including the S5. So if "last gen" is the S5, what is "current gen" hardware? I am not trying to pick a fight, just trying to understand.

I consider the S5, and SP20, and Aavalon 4.1 to be "current gen". I would put the S3 in the "last gen" category. That's just me though.

Thanks again for the prize you supply, suchmoon.

[Last of the V8s]

I just took that to mean latest gen.

Bitcoinwisdom -3.49% with 9.4 hours to go - maybe no one gets it this time round

I will do the no change rule for next adjustment.  Less work and less confusion.

I suggest that everyone wait 2 days to do a pick so they can see the - or + trend.



Last gen  = lastest gen  say s-5 sp20 or avalon 4.1  I think

33 blocks and -3.45%

[judypug1956]

Shapeshift looks good at the moment.

FINAL LIST OF ENTRIES FOR THE 0.1 BTC REWARD

New entries are not accepted anymore but speculation is welcome.

Please take a minute to find your name in the list and verify the numbers. Let me know if you see anything wrong.

The pack is tight this time (rollover less likely) and BitcoinWisdom shows -1.67% trending a bit higher.

Thank you for participating.

[philipma1957]

we have 13 blocks to go and shapeshift is the current leader




he has -3.26 to 3.50%


tss has -3.01 to -3.25%


- 3.51 to 4.00%  are empty

armedmilitia is at -4.01 to -4.25%  some long blocks could be helpful to him

Last of the v8s  is at -2.76% to -3.00%  he needs short blocks

Good luck to those above as we near the finish
