My fast guess is both are low as sp20's and   s-4's have sold very well. I hope for under 5%   this Jump !


Oh here are the jumps since June 2014 when  the s-1 stopped selling and the s-3 started to sell

Jun 29 2014   16,818,461,371   24.93%   120,391,236 GH/s     the s-1 stopped and the s-3 sales started around this time frame.
Jun 18 2014   13,462,580,115   14.51%    96,368,902 GH/s


I do an average for diff from Jul 12 2014 to now as this time frame represents the conversion from 2 watt gear to 1 watt of less gear.

Soon I may pick a new point since .6 watt gear is becoming  more available.

If we get a negative last time and a slow one this time it will be a dream on mining difficulty.  I agree we will see a little jump though.

I would say say it's going to be 5-10% this time. What do I win if I'm right? Smiley

yeah  .6 watt gear will sell to a lot of people. I have a 4k-5k power limit in my garage.

 Thus sp20's downclocked to .55 watts are a natural upgrade for me from s-3's  I am not the only one.

With .1 electricity I could not justify changing yet.  I do admit I love my sp20.  Bitmain and SP are my favorite companies on current gen.  With winter have went over 11k watts currently used for mining.  Getting ready to rewire my computer network where I have access to 6 k watts or so more, doubt i use it but wiring networking in case so I could quickly expand.

yeah the second one came today. they do .55  and .56 downclocked to about 180 watts a pcie connector I use around 740 -760 watts and hash about 1330-1360 on each one.

so 1500 watts gives me 2680 gh.   I can run 6 or 7 of them the whole winter. very tempting to turn  to them rather then running 12 s-3's  lot more hash.

this may be my last in house miner.

so realistically how loud are they really.. would you say you can keep 6 sp20's in a spare upstairs bedroom?

Most likely a regular bedroom will not be wired electrical for 6.  And it depends if you use a underclock its much quieter, if letting stock it is quite loud.

Not unless you have extension cords running from every other room in the house to the spare bedroom. You'd be very lucky to have 2 in there without tripping the breaker. And you'd better have great ventilation in that room or it will make a sauna seem like an alpine meadow in springtime.

Why don't u guys mod the sp20? atop of the fan make a cut for a second 12cm sucking fan. At the sides mount other 12cm fans... outside the case fans, but with screws to the case...

A) you need to underclock set fan at 40 or 50  
B) if the bedroom door shuts and the room has enough windows to stay cool  maybe

my two are set at about 4x 180 watts vs max of 4 x 288 watts
I use  about 760 watts at the kwatt meter for each one  or 1500 watt for about 2700gh.  so you would need a lot of power to run 6 even underclocked.

As for modding it can be done but I personally don't need to do this.

Because they say opening it up voids warranty.     So kinda not something you would do till warranty runs out.

I wonder who swithched OFF ~30ph in basically one day. It plunged from 304 to 274PH.
Network was kind of weird in the last month or so-sudden surges followed by deep plunges in hashing speed.
I still stay by my conviction that it would pay for someone to purchase calls on bitcoin, then purchase hashing, switch it off and see a spike in bitcoin price soon afterwards. Rinse and repeat.

A large dragon farm?
A large s-2 farm?

Older bitfury farm?

A little of each?

end of june 2014 the network had 120ph   almost all of that gear is out dated .  since most of it was 1.2 to 2.5 watt gear.

so when we saw the network at 300ph the other day I would think the higher watt gear was almost all done for.  but a few farms may have shut down this diff setting.

S2 and SP10 were available since April-May, and these two were probably responsible for a large part of growth between May-June. I bought a bunch of both in May. All are still profitable today. So I would say only 50-60 PH/s is really outdated and will be quickly replaced with cheap S4s, SP-somethings etc.

Also don't underestimate the variance. Some of these spikes over the last few weeks could have been just that. I doubt anyone is flipping a 20 PH/s switch on/off.

A 30PH dip can easily be attributed to variance due to bad luck... especially when that missing 30PH suddenly shows back up on the network a day or two later.

You are right about someday we will see a bump from Dragon's going offline.   It's hard to tell when as most are in very cheap electricity places, but if done proper they do have a decent cooling cost.
