Can someone look through my spreadsheet to verify my estimates on the SP30?

you got it wrong,it's 10m3 volume, even better Grin

Now that just seems like unnecessary tech-cruelty.

I vote for a more freerange keeping of your spondoolies units.

After all, the quality of your minted bitcoins will suffer when the fans cant turn freely in cool air, as they wish.

Raskul has a good approach there.

Care to elaborate which "trollish assumptions" I have made? Stable bitcoin price? Lower than average difficulty increase?
If anything, I was very conservative with the numbers.

Please respond to the estimates I made rather than resorting to name calling.

all crystal ball gazing and trollish predictions of positive/negative return on investment, should have their own thread and not be added to any manufacturer thread. this thread is for the discussion of Spondoolies-Tech and their hardware, not for predictions of the future. People will do their own calculations, and make up their own minds.

If you feel the need to make assumptions on what this hardwear will/will not do, then please start your own thread and do not spread FUD here.

thank you and happy Easter.

I'm sorry if it appears I'm trolling, but I am not.
This is a relatively expensive investment and any investment should be valued based on its estimated cash flows. Calling it "crystal ball gazing" doesn't change the fact that anyone that drops their BTC/Dollars on it is expecting to at least get their money back.

Again, I used very conservative estimates of difficulty increase and assumed BTC price stability. I am also excited about new technologies and appreciate the way that Spondoolies is doing their business, but why am I being flamed for examining the cost/benefit of the product?

If you have such care for the welfare of the world, why not join Médecins Sans Frontières. I'm sure with your moral high-ground and foresight, you will go a long way.
Perhaps you can tell me next week lotto numbers while you calculate how long it takes me to put you on ignore.

Coming out of nowhere and posting the same thing in 2 threads(but not on KnC thread too who is also selling some pre-orders) makes me think that you are paid by one of the competitor hardware manufacturer and the only one that comes to mind is KnC since they are the only one with equipment that is on pre-order. Also it seems that you posted this after the Special Easter Egg offer for KnC customers. It's more than obvious that you are paid by KnC.

Vitalious:

Your assumptions in the spreadsheet suggest that in 4 months,  manufacturers will be able to pump out enough hardware to replicate the entire current(as of today) bitcoin network every 2 weeks.  I don't see any technology changes that will allow for that much hashpower to be produced.  If you disagree,  you should run away from EVERY ASIC manufacturer out there.

Defenders of Spondollies: Difficulty and the profitability of the machine certainly does have a place in this thread.  I think asking "is this a good buy?"  has been relevant in most other threads.  This guy may be a troll,  but I'd rather not go on a witch hunt for every person who is questioning if the growth of the hashrate makes pre-orders unprofitable.

i'm gonna buy an extractor running @ 1000m3/H. If it's not enough air flow, i will add an AC so the temperature inside the room which may not be other 25°C. I'm gonna get 3x SP10 tomorrow so i'll update with real number cause all I do here is speculation. It's bad.

I'm not a troll, I just want to know there's a decent chance of me at least breaking even.
My 19% difficulty estimate was based on the last 6 month average difficulty increase. That's lower than last year, which is 23%.

If I'm way off in assuming last 6 month difficulty growth into the next 6 months, then I welcome criticism. I want to invest in mining hardware as well but I need to know I'm not chasing unrealistic profits.

You are way off. There was a huge spike in difficulty during the last six months which is no longer occurring, and is unlikely to occur again. (Though anything is possible.)

Historically bitcoin mining has never repeated itself or been predictable.

I think it will be much less than 20% increase per change simply due to the fact that there seems to be much less competition for gen 3 asics (<0.5w/gh) but I could be wrong.

For the ST guys...

How does the start.ST.com site work when your miners are hosted remotely (in a DC for example).

Would you need to use a VPN so you pull an IP on the same LAN subnet?

now, even the fan are working at their lowest level I would need to extract at least 170m3/h per SP10. Give then fact that this unit has 80-90% efficiency it would mean that I have to extract at least 150m3/h per SP10 and lets say 300m3/h for SP30. I need to extract 450m3/H * 3 batch = 1350 m3/h !!!!!
The room is only 10m3, it mean that i will need renew the air of the room more than twice a minute to keep the temp inside same as outside the room.
This is ridiculous.... Roll Eyes
I use one of these http://www.tlc-direct.co.uk/Products/SLTD500SILENT.html silenced 6" duct fan to shift 500m3/h.
You could try using 3. They only draw 50W running flat-out.
They make them in a 8" version too. You might get away with using just two of those.
Good Luck !

We are now working on a full-fledged cloud control panel, which will allow creating accounts and linking them with your miners wherever they are, allowing to solve this exact issue.
More details to follow soon.

This sounds awesome, but what about the security risk of centralizing the configuration of so many miners in a public cloud?

ST, do you imagine a time in the future where you ship only from stock?

It sounds as if you have built a solid product, but the whole pre-order process ads an enormous amount of additional speculation to an already highly speculative investment.

Thank you for your compliment.
We build, test and ship as fast as we can.
You need to consider lead times. It was discussed last time here:
