great for me, maybe my s7 can stay profitable for just a little while more perhaps if bitmain keeps cranking out miners as they have been hashrate won't keep dropping... I just hope the EDA is fixed so this sloshing in hashpower stops. Bad for both chains.

yeah it makes for a lot of action or volatility I guess traders like it.

according to http://bitcointicker.co/networkstats/  with 550 block left we are -4.4%

viabtc.com

at this link

https://pool.viabtc.com/

has
Coin_____  Network Hashrate
BTC...............   7033p 
BCC...............    806p

I think I will attempt  to run contest next jump  giving away the trezor  and using  bitcointicker  as the tracking info.

I am having trouble with exact  block the new diff started at.

https://bitcoincharts.com/

this claims  block 481824  was first block of new diff

Blocks   481823
Total BTC   16.523M
 
Difficulty   923233068449
Estimated   887736944047 in 1 blks
 
Network total   7983858.406 Thash/s
Blocks/hour   7.25 / 497 s


if true

482085 (Main Chain)   2017-08-26 16:27:59
481824 (Main Chain)   2017-08-24 01:57:37

261 blocks made in    24 + 24 + 14.5 hours


261/60.5 = 4.314 blocks an hour vs 6

4.314/6

71.9 %

or a 28.1% drop  at the 261 block number

so  we know the hash is at bcc/bch   and can shift back

but a 28.1% drop in diff  and price of coin over 4100 usd for btc would be a nice gain for miners

483840 (Main Chain)   2017-09-06 13:23:15
483840 (Main Chain)   2017-09-06 13:23:15

481824 (Main Chain)   2017-08-24 01:57:37

2016 blocks in 13 days and 11.5 hours.

1953 would be 0 % so a 3.22% jump


so from -28% to + 3.22 %

in about 11 days time

we are watching very interesting manipulation of hash rates .

oh bcc is getting a big pump today

Have you seen the site bitcoin.sipa.be yet, Phil? Seems like a somewhat good indicator of difficulty that has charts somewhat like the ones on Bitcoinwisdom. Not sure how accurate they are, however, and they don't seem to provide any specific values.

I think I found a site we can use .

It provides btc and bcc info.

My plan is to show the charts for this jump then start contest again

Just had a look at the 9 month chart on bitcoinwisdom...wow that is pretty crazy.  If bitcoin price goes down to 2500 lets say, and diff keeps truckin` then its safe to say a lot of S7's will be going into retirement.....

Well  if coins stay at 3800  and diff jumps 20%

a huge swing will go to BCC/BCH

at the moment

8233ph = BTC           coin price is 3900

 974ph = BCC/BCH   coin price is   514

BTC diff is pushing a big diff jump

BCH diff is flat 

8233/974 =  8.45 

8.45 x 514 =  4344



so when that big diff jumps for btc   if btc is  at 3900 and bcc/bch  is at  514      a lot of hash will switch to BCC 

basically for every 3900 you earn with btc you would earn 4344 for bcc/bch

this is really dangerous may make market nuts.

I would have thought the BCC "Emergency Difficulty Adjustment" (as I understand it) would have "expired" by now and it would be back to the normal 2016 block adjustment interval. Right now it appears that BCC still needs this "crutch"?

That seems like a poor situation long term, though maybe the "Emergency" only needs to last a while longer.

I can understand why BCC seemed desirable to Bitmain since it would supposedly increase the set of folks that would want an S9 (i.e. BCC-only miners).

I'm guessing they're keeping this "crutch" up only so that people will actually mine the coin. Without it, it seems not a whole lot of people would mine on that chain and thus they're likely keeping this in place just to incentivize people to mine there. Realistically this should've lasted at most a week but it seems like this emergency is extremely prolonged or there's miners involved/incompetent devs.

the problem will show when BTC  jumps 20%  if it does not rise to about 4350  BCC  is the clear coin to mine



viabtc.com

has 

 btc          at 9580ph  3900 usd
 bcc/bch   at   900ph   500 usd 

https://bitinfocharts.com/comparison/bitcoin-difficulty.html#3m


 diff is 922   
 diff is 119     


the diff will jump to 1106 for btc


 1106/119       9.30 to 1   so 500 x 9.30 = 4650


 vs   922/119   7.75 to 1 so 500 x 7.75 =  3875


so right now   bcc is 500 btc is 3900

current diff is               7.75 to 1  btc is slightly better to mine


once diff jumps   btc to bcc/bch  needs to be 4605 to 500  to be better.     to mine  so we are going to see swings.



viabtc offers auto switching:


  so a lot of hash may switch to bcc next jump

maybe bcc prices crashes


or maybe  btc price rises

bitcoinwisdom seems to be back up

While this is quite welcome, the BTC price is clearly stuck way in the past.....

 I suspect some already have - they're NOT profitable unless you have SUPER cheap electric.

[leowonderful]

My S7 is still truckin along barely profitable right now... thinking of just throwing it in the miner museum with a few other old relics. I'm surprised these things have made it so far, two years of mining... shame Bitmain doesn't make anything nearly as reliable these days.

BTCC suspends trading and price plunged to $2500 temporarily on the exchange... with the difficulty rises combined with that I don't see this thing making it that far anymore sadly.

[Last of the V8s]

sorry am very out of the loop it seems. these Japanese mining companies announcing 7nm chips, that's realistic now suddenly is it?

[QuintLeo]

It's ONE company "GMO", and I believe their originally announced May 2018 timeframe was way optimistic.
They seem to have toned the timeframe back to "have working silicon in 2018" which sounds like they are targeting TAPE-OUT by the end of 2018 and might be a viable target (that would put actual PRODUCTION into 1Q or 2Q of 2019).

 They seem to have also had some bad timing on when to get involved, with the recent news out of China - unless China DOES in fact ban Bitcoin and it puts Bitmain/BW.COM/EBit and the other smaller Chinese miner makers out of business (Innosilicon will probably survive, they'll go back to being a custom design house like they were before they started doing Cryptocoin ASIC).

[philipma1957]

A lot of action.

coinbase dropped under 3000

  2975  back to 3352


on hashnest  the  s-7   was  making good money  when coins were 4500 plus

it is still at the 49% level

what does this mean?  it means bitmain is still whaling as now one checks to see if they run s-9's and charge for s-7's

[TheYankeesWin!]

Hey Phil  the game will start next jump?

They are back
