At $0.02 per KW, you are profiting on average $320.00 per month for each S7
You have to recoup your initial "investment" (purchase price of hardware + psu) before you see any profit. Even with 2 cent power (which is rare in and of itself) you won't see profit for over a year. That's why I mention ROI even at low power rates. New hardware purchased at retail price just doesn't make any sense right now.
Not necessarily. If you plan on selling the machine, say at half price, you more or less get back your initial investment back at that point. And PSUs.... I reuse what I can, but that's assume you're replacing/upgrading capacity, not adding.
Anyways... my plan is to mine for 6 months, and then see what a used S7 will go for. If I can replace all my miners with a single S7, that's a win, too!
I'm just a hobby guy, though. This is not my day job. Everyone's circumstances are different...
That was my train of thought also. I have my little 'hobby mine' of 2xS3 and an S5 running around 1.8TH avg at just under 1200W. Once the used S7 machines start to hit the marketplace, hopefully at sub $1k prices, I should be able to more than double my hash for the same amount of power. Any amount I can get from reselling the S3/5 machines will help offset the upgrade.
That's also assuming a used market develops for the S7 in 4-6 months. Next week's new technology could turn into vaporware or unobtanium and the S7s will dominate through the halving. Then again, new tech (SP50, et al) could transition the mining game into more co-op operations, even at the hobby level.
It's nice to see Spondoolie selling something, at least it's not just Bitmain that we have access to. They make great hardware. I had an SP31, never an issue. Funny thing is I bought it used for 1200, mined for 5 months and sold it for 2k. Sure I'll never make out like that again. Took that money and ordered a s7. But this sp50 is a co-op machine for sure, unless your a huge farm in China, Venezuela or Greenland. Still waiting to find out the price of it. But they should use the same .15j chips and make a 5, 10 or 15th box for the average joe unless one takes out a second mortgage and uses 80% of a standard 200amp main at your house:)
Just got this email from Spondoolie
Thank you for your email and your interest in the SP50. We are excited and proud to unveil our next generation machine as a breakthrough product for industrial mining.
With its extremely low power consumption and modular design the SP50 has been specifically designed for maximum power efficiency and ease of management.
Initially the SP50 will be offered in limited quantities only to a select group of customers. As we scale up production we hope to offer the SP50 to a wider market. At that time we will publish pricing and shipping terms.
We thank you for your interest in the SP50 and look forward to working with you.
Regards,
Barbara
