Probably nearly no discount at all. They'll just yawn like it happens every day and offer you 3.1% discount. A substantial amount of the network is used gear, and not all of it will turn off; Most people with S7s and Avalon 6s must have pretty cheap electricity, since difficulty hasn't really moved much at all. Difficulty will almost certainly drop, but we don't know how much at this point. It could go from 1% to 10%, as this is a pretty uncertain point. Even the network hashrate shows this as hashpower has been in flux for a few days now.

Besides, if you want to replace the 20PH with S9 hardware, you'll need to purchase at least 1700 of them. Even with a discount, that will be significant money to send off to Bitmain. I wonder what kind of terms you get if you offer to buy 1700 S9 units from Bitmain?

well  +1 %  0% -2%  all work for those that purchased s-9's early.

remember  1200ph of the network is old gear.

 400PH older then s-7 
 800ph s-7+ avalon 6 
 400 ph s-9

all approximate but not far off.

So  you had cheap power 5.646 cents cents  and 20ph in s-5's

before the ½ ing your farm would be earning  14912 usd a day
after the ½ ing your farm would be earning        3.40 usd per day

you figure I will mine for a bit as I am not losing  so you mine 10 days.

and you now decide I will swap out s-5's slowly for s-9's

why slowly you are not losing money so why rush.

As for why aren't you listing the 20,000 s-5's on ebay  simple you are a chinese farm  and you don't list on ebay

I'm wondering the same if finally some miners are going offline.  I thought leading up to halving we would see a lot bigger increase which I was happily wrong on. Really it is pretty pretty slow on dropping off on old gear.   I would really like to see drop off how much is home/hobby miners vs big miners.  If you think about it a lot of these bigger mines spent a good amount of money upfront for info structure (cooling, wiring, etc).    So it would make sense they might re-invest.

I am happy with BTC price though it's been pretty steady.   No big drop off on value side has been a great thing for those long term holding. 

It may be that we are starting to see an effect of the halving on difficulty. Both bitcoinwisdom (-1.98%) and nextdifficulty (-2.1%) are showing difficulty decreases. We'll have to see how it actually works over the next 12-13 days, but this might actually be "real".

BTC price still at $673.

  As I have mentioned graphs right now seem to be wrong:

no new info for 9 days



the gray line  on bitcoinwisdom is not correct.
we never did the 1650ph it shows for yesterday

So two of three major sites are wrong

If many people really switching off, you should see increased supply of such mining equipment for sale on ebay, mostly S4, S5 and S7 stuff, the older stuff had to mine on free electricity even before the halving I guess. Some might switch off and just wait if price increase, but there should be enought of those who try to sell on ebay instead thus increasing the supply of older mining equipment on market. I dont see any dramatic reduction on ebays prices so far, which increased supply should make.

About Bitmain replacing S7s for S9s on its own mining farm, it makes most sence to replace and sell the S7s before you even start selling the S9s. So I guess they run S9s only already and the increased difficulty in last months is the new Bitmain S9s mining farm equealing to their own 3x hashrate increase, while the replaced S7s already sold.

So, the question in my mind is: How closely will the deployment of the S9's that are for sale match the shutdown of less efficient gear that should fall off the network? The halving must have rendered at least some gear unprofitable to run. The price of BTC doesn't seem to be going anywhere for the moment. This current difficulty period is all at 12.5BTC reward. The only unknown for the next 2 weeks is BTC price, and that appears moderately stable.

I wonder the extent to which Bitmain has been replacing S7's with equivalent hash (i.e. stable hashrate), and not stable power consumption (2-3x hashrate increase).

Thanks again for running this, Phil. 

Okay first off VRobb  was the winner of last contest 50 usd in btc.

 So  a >>>>>     New game.

PICKS BEGIN AT 1116


When game began about 20 months ago coins were about 200 usd  0.10 btc was about 20 usd. we paid  in .10 btc numbers.  Our first donator to the game  spent over 2.8 coins.  I have been the sole payer for the last 4 months and have paid .9 coins  so 3.7 coins have been awarded for free, nada, nothing  no cost.  I am still able to do this due to my signature fee.  Which I put into payments here.


First rule is I decide all rules since it is a free chance to get some coin.
Second rule is you need to be  a forum member since April 15th of 2016
Third rule is you need to have made 30 posts.  I will read them and decide if you appear to be real.
Fourth rule is if I think you are double dipping your picks won't be allowed
Fifth rule is we open picks at 1116 and end picks at 716   just about 2.5 days to pick.
Sixth rule is  this is for fun so I tend to allow off topic and don't delete very much.
Seventh rule is your pick should look like  -1.2 = philipma1957 or   +1.2 = philipma1957
Eight rule is  if you pick a used pick I will assign a pick to you and you are stuck with the one I assign.
Ninth rule no pick changes
Tenth rule no pre picks via pm's
Eleven rule no late picks.

Anything I missed above feel free to mention.

I self mod due to seriouscoin
I always pick -1.2 due to seriouscoin

current numbers above  I notice some graph issues between two websites.
bitcoinwisdom seems to have a false spike

I need to look into the issue.  if we need to change sites for official diff numbers I will
