[..]
Let's say that I did purchase one, however. At the current network difficulty and BTC exchange rate, that S5 would expect to make ~$3.25 a day before power costs. ROI would be ~123 days. Using a very conservative network difficulty adjustment value of 2%, we're up to ~136 days. That right there should have convinced me not to purchase one in the first place... and I assumed free power in my numbers.

That's lack of enterpreneurism...

Common business reaches ROI 2-3 years after initial investment.

We were (are?) seeing month-scale ROIs because of the highly speculative price of bitcoin.

If (when) bitcoin becomes more mainstream, expect ROI in a year or two... not less

Disagree, but only by time frame ROI will be 8 months not 12 to 24 for 8 cent power.

60, 90, 120 days for ROI is pretty much over.

I have higher power cost then many So ROI will be a year for me.
When I buy I time for my winter power price which is 10 cents net.

I Like to mine from October 1 to March 31 then sell off the gear.

Aside for above.

Bitmaintech has not been the supervillian people make them out to be I know many people hate on them.

In fact I have decided to hold off on my s-5 is it working or dead thread.
I did one for the sp20 and that gear looks to be over 92% alive according to info on more then 300 pieces of gear.
I read this thread and I see a lot of angry people. I do not want to open a thread on it works or it is dead and have to edit hundreds of complaints due to the hate against them.
I would like to do it with the s-5 maybe I will start it this week.

Ive hit RoI with all my S5 i bought in Jan this year. but back then i got them all for around the Xmass price and just got two more one didn't work but i was able to fix it and its still hashing a way at any speed i use in a safe range the other one was just a give me that was kind of a replacement for but it stopped a week after i got it but it was free so no complaints other then what bitmain did in price for parts , im over it now . no there not supervillian that's business and how it is.if they wanted to and could have from the start and still sold them but they looked out for us charge right off the bat 800 per miner . id look at it that way .

i have to say i have been in ROI with my s3s i got last july, which i used the btc profit from them to buy the s5. so everything i have has been paid for.

its not that bitmain is a supervillian.. they just need to pick a price that makes them profit and stick with it..
these weekly price adjustments make them look bad. specially for the people that buy at one price and 2 or 3 days later its considerably cheaper..

the s5 still has a lot of life left.. so its still a good buy..
at 10c a KWH it will make a profit well into 115 billion difficulty.

In a way it has been kinda a reward for customers who supported product since early. Not only have some of us hit ROI machine is worth more then we paid.... so very early customers yes very good at that there.

I hope they go back down since BTC went down some, but they are a business I'm sure they have a plan without my 2 cents.
