No ROI buying S3 and without electricity FEE ?¿??¿?¿?

[Bitsaurus]

analog miners?   first time I hear about them.......      Why people dont care anymore?   Low hashrate ? 

Thanks!

BrianM is either using a translator or doesn't have a good mastery of English.  To my knowledge there is no such thing as an analog miner - not even sure what he could have even meant.

The next Batch of S3 is not due for another 2 weeks and difficulty is about to jump to 20 billion, so by then it may be 21 or 22 billion.

English isn´t my main language too but,  it´s first time for me  seeing "analog asic"....   

Im wondering what he was trying to say..............    Maybe DIY asic ?  I have seen a few proyects about DIY minners.......


Thanks all people is helping in this thread!!!

I find this one to be more accurate:

What do you use as the profitability decline per year?

Im really disapointed...... just wanting to buy a few  Antminer S3  cause I can use them  at work  where I have no electricity fee.........

I was seeing the ROI ,  using this calculator:

Please,  can someone help me???   I dont understand why  ROI is impossible  even  without electricity fee........  or this calculator is not accurate??? 

Thanks!!!

Please accept the truth that mining isn't profitable for small time investor. If you order a million S3 they would give u 70% discount.

- difficulty near 15%  in the best of the scenario.......
- No electricity fee
- ROI in 5-6 months ,  and later,  about 400 € profit  if  difficulty is 15% to end of days

I dont see the business....... Only can Truly ROI  if bitcoin  rockets to 1000 USD...

Does that mean S3-B6 with a ship date of 12-Aug is sold out? Or is there a factor applied to the published ship date?

I built a spreadsheet for the no electricity model. Assumes 10% increase in difficulty every 11 days. If I order the miner and put them in production on Aug 18 (the next bump date in my spreadsheet) then the payback by Dec 6. This assumes the miner is .66 BTC to include shipping and half of the PS is $65. By Dec 6, the miner is making a whopping 2.32 a day.

If I change the assumptions to 8% difficulty increase and 12 days per bump then it pays back by mid November in 100 days. It stays over $2/day until February. My landlord is not able to track electricity usage at the apartment level.

With analog you get infinite step instead of only 1's and zeroes. So you can have hash a lot when mining with variable steplenght also noise is not a problem it will be filtered out with bandpass and there will be possible of makeing more hash, if the filters are outdated, so no more useless gear, just update the filters and you can continnie mining
