1  Bitcoin / Hardware / Re: [ANN] Spondoolies-Tech launches a new line of ASIC miners - Best W/GH/s ratio on: April 21, 2014, 07:42:16 PM
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 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.

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.

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?

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

you are practising crystal ball reading? that's 2 threads you have spammed with your trollish assumptions.
you hungry?

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.

I did the math on the SP30 (the 3x package) and it doesn't look like this hardware will ROI with current prices.
Please correct me if I'm wrong:

You're in RoadStress group sale thread. Did you read the PM ?
The hardware cost is much cheaper...

Guy, I have a lot of respect for what you do (and I'm originally from Israel as well), but even adjusted to $4995 per unit, it appears the SP30 doesn't ROI.
Again, this is assuming 19% difficulty increase every 2 weeks, current BTC prices, and timely delivery.

I encourage people to look through my spreadsheet and verify my calculations.

I live nearby their supposed office.

If someone can point me to an address, I can pay them a friendly visit.
