That SP20 is a cute little rig. How many BTC is it making a day ?
You already know the answer to that question. twenty five cents a day by Easter more likely 2 dollars a day by April 15th, but your 25 cent estimate is possible.

On one of my SP20's a firmware update 2.5.27 became available this afternoon. Has anyone upgraded to this version yet?
Current firmware version: 2.5.26 Latest available firmware version: 2.5.27
Wierd, I upgraded to that 4 days ago. mine was upgradeable 3 or 4 days ago I did nothing so far. I have some questions. First is the new firmware better in any way. Second and not on point do you use the little mini sd card or do you not bother? I will have 4 or 5 of these soon and I wondered if I need to use the little sd card option.

I looked at the numbers and either bitcoin price has to increase to $600 or difficulty has to go down 20-30% for current NEW miners to make sense economically. I wish Spond would position SP20 as a 1.5 TH miner at 1000W for $600, but they know their bill of goods and I don't , so this may be impossible. BTW, Guy Corem thinks that current miners (0.5-0.7w/Gh) are all becoming uneconomical in the near term. https://www.coindesk.com/bitcoin-price-decline-sparks-rare-mining-difficulty-drop/Guy Corem, CEO of ASIC-designer Spondoolies-Tech explained:
"Under the current bitcoin value, mining gear efficiency of 0.5–0.7 J/GH range and energy cost, we'll reach equilibrium very soon."
In layman's terms, with bitcoin prices in the sub-$400 range, mining at a difficulty level of 40,000,000,000-plus simply does not make economic sense with current-generation hardware. . I have done a lot of math on this and frankly network growth is going flat. Or BTC will die. Flat price growth and flat diff staying under 45 means an sp20 makes money. but not a lot of money.

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.

they run way better under watted.
which means you get 750 watts and 1350 gh
think of driving a car with your foot pressing the gas at full speed. yeah the car does 150 kilometers per hour , but it is risky and burns a lot of gas.
drive at 100 kilometers per hour the ride is safer easy to control and you get much better gas mileage.
so calculate using 750 watts and 1350 gh . not 1200 watts and 1700 gh
Sir, I agree with you, but I think SP20 gives 1700 GH/s underclocked and not overclocked, if I'm not wrong??? Maybe? I tested the shit out of this gear. max setting is 288 watts x 4 = 1152 / .9 if you have a really good psu that is 1280 watts and 1710-1725 gh I used the evga 1600 p2 psu high end really good . set fan at 100 . I used 1310 watts at the k-watt meter not 1280 watts and it never past 1750 runs really hot burns a shit load of power. A number of 1725-1750 for max is correct and frankly pretty nutty to try for. like I said 750 watts and 1350 gh this will allow the gear to just keep on working day in and day out with very little attention or care.

third one has arrived and is mining. fourth to arrive on Thurs. I have reached A funny problem. do I sell every s-3 and go for 6 sp20's rather then running 4 sp20's and 6 s-3's

I am not really 10 th . I am 5.6th with 2 sp20's coming in I will be at 8.3th
I am trying a different renting method from nice hash and west hash.
So sometimes and extra 4th shows up. Sometimes it does not.
8.3TH/s is a substantial hashpower for a hobbyist and should ensure a good return as a long term investment (provided you are holding onto your coins) I opted for the SP31 as I am all used up on PSU's and if I were to order more SP20's, i'd have needed to get more PSU's SP31 comes with power packs built in, so it is as I like it... plug it in and leave it. I would like one of the sp31's, but I do resell all my gear to lower power cost users. So the sp20's will be easier to ship and sell in 5 -7 months.

Yup. Will the next jump be negative as well ? We should only be so lucky. It is possible. If you go back to JULY 1st most of the network was 2 watt gear. We have not grown so fast since July because people pulled 2 watt gear out and replaced with 1 watt and .8 watt gear. Now I have to think the network is 1.2 watt or less on average. So a lot of the older gear is shutting down to be replaced be .6 watt gear or better. Yeah you sold a lot of sp20's and a lot of s-4's even s-3's sold last jump. But all s-1's are going even low watt mods are going offline all dragon miners are going offline lastly s-2s are shutting down. So low growth will stay a while more. At least I hope so.

Hey guys, I have found a Sale at Spondoolies as they are currently providing with a 15 SP20 Miners' Mini Farm to be bought and it costs nearly $10.4k to buy it as some sort of sale is going on. Also checked the calculations on most of the sites and got that if the difficulty remains the same, then it is possible for me to get my ROI in just 3 months, and the rest is the profit... Waiting especially for your take on this, allcoinminer... Here's the link I'm giving for reference regarding the same: http://www.spondoolies-tech.com/products/sp20-mini-farm-batch-1my reply is very simple that farm would be a decent shot if you have good power prices. if it is coming up to winter for you (no cooling needed) I own 2 sp20's going to be 4 in a few days. I run them underclocked . I use about 750 watts for 1 and get about 1350 gh 15 x 750 =11250 watts 15 x 1350 gh =20250gh or 20.25 th depending on diff growth power cost btc price this setup stands a very good chance at a profit. Thank you so much for your reply sir. I have some more questions I would like to ask, please reply to them if you don't mind... Actually, I live in India and my dad have been paying all electricity bills since my birth, and till today I don't actually know what's the cost for power, i.e. $/kWh he's been paying. Regarding SP20, I have seen that those miners can give nearly 1.7 GH/s and overclocking can get me up to 2.2 GH/s if I am not wrong, but yes, I need 1200 Watts of power to be sent to 1 miner and if I ain't wrong, if I get 1.7 GH/s from 1 miner, then with 15 miners, I must be getting 25 TH/s which will gain me $43,571.03 annually based on current difficulty and if I subtract the power expenses that I estimate and put in at Coinwarz, the exact profit it shows is $27,803.03 per year and my power Cost will be $15,768.00, making me a return of up to 270% and my profit % will be 170%. Are all my estimates correct? I will ask my dad and will post here regarding Power Cost, but based on my estimates, can you please evaluate everything again and tell me whether it's an opportunity or a loophole? Reference of my search: http://www.coinwarz.com/calculators/bitcoin-mining-calculator/?h=25000&p=18000&pc=0.10&pf=0.00&d=40007470271.27130000&r=25.00000000&er=379.85000000&hc=10425they run way better under watted. which means you get 750 watts and 1350 gh think of driving a car with your foot pressing the gas at full speed. yeah the car does 150 kilometers per hour , but it is risky and burns a lot of gas. drive at 100 kilometers per hour the ride is safer easy to control and you get much better gas mileage. so calculate using 750 watts and 1350 gh . not 1200 watts and 1700 gh

Please contact us with your order ID via sales@ or through PM
Thanks Guy, all is well ... SP20 arrived today ... and is hashing away. I expect it to take a couple of days to settle down, but seems happy at 1.67Ths right now. 6 months in the BTC space has seen great improvements (sorry to state the obvious) ... with the SP20 footprint at 1.7Ths being so much smaller than the original June SP10 at 1.4Ths, power consumption has of course also improved. This girl loves you and your company Guy https://www.youtube.com/watch?v=t0JC4ddadAo (probably old news). As raskul and others have said ... home miner(s) will be winter heater(s) ... and the UK is cooling down nicely right now. Just waiting now for the next gen machines to replace the hosted miners I have ... and into 2015 we go ... it's my birthday next wednesday = the BIG 40, I want one of those 5.5TH/s beasts. are they shipping yet? Happy birthday! I would love to be 40. Hell even 50 would be nice, I will be 58 in Jan.

so stock it is only working at 1.4 TH/S not 1.7 TH/S as they listed ?
you have a choice of watt settings. 70 to 288 288 is max and will do more then 1700 maybe 1750 problem with this 288 x 4 = or 1152 watts very few pcie wires run well at that setting evga 1300 and evga 1600 can do 250 all day all night for months. I have done it with them. I have no other psu that will do that with stock wires. So if you want max setting of 288 to get your 1750 you are really pushing the machine Like I said it is their marketing decision. I would say this is a 1600gh machine and with a carefull overclock it does 1725. Since I set my machine at 180 watts x 4 = 720 draw or 750 at kwatt meter vs 288 x 4 = 1152 draw or 1300 at kwatt meter.
I don't care a single bit about the difficulty to reach max gh.I found this to be very true with gpus back in the day: you may get .5gh with a hd7970 and use 170 watts crank it to the max you get .66gh and use 300 watts. Hard on the gear hard on your ears . ( < That reads like porn not meant to) So I underclock and I am happy. Those looking to squeeze everything out of this machine will need really good pcie wires really good psu's and will be maxed under 1800gh for sure.

second one in. third one comes today. yeah the only thing I see wrong with this gear is the marketing should list it as a 1600gh miner with possible overclock to 1700 I got mine to 1710 with fan on 100 and an evga 1600 p2 psu it sucks a lot of power doing this. Ran pretty hot. my watts per gh drop from .55-56 to .71-72 At that point for power the s-3's are competitive . For me I knew I was going to clock it lower and did not care that it struggles to go to 1710. my watt settings are at 181 vs 288 and the gear runs really well. note temps this with garage door closed all numbers are good safe etc

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.
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? 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.
