all of my E3 hashing fine as of today Dec-08-2020
YES all my Antminer E3 from the first few batches are still working without any issues.
Still works? Strange seems that there is conflicting info, a few days ago there were 2 people who claimed that their E3 stopped mining on the last DAG. I figured there would be tens of thousands of these units go offline and we should see a hashrate reduction. However looking at,
https://etherscan.io/chart/hashrateLooks like the hashrate is about to hit a record high again. So obviously it doesn't seem they the E3 have died...yet
Just wondering did you ever ROI on your E3? I was going to order one but the first batch sold out and the later batch was basically double the price. I am wondering if I ever would of ROI if I invested in the E3.
Im sure all my E3 earned me way more money what i paid for those units . My electricity rate is 12cents from June to September , all other months is between 7-8 cents . Im Doing mining as a business ...
I was lucky , ordered my E3 from the very first batches , if i remember right , in 2018 summer first batches was around 800$ each with shipping or something very close to that . Some gpu or mem went out on those blades , but still all of them hashing . I have those units in the past 25 months if i remember right ...
Lets do a little math with 10 unit and average hashrate around 170MH/s... with 780 watts of power usage ... and current ETH price/difficulty calculation ...
Total investment 10x800=8000$Total hashrate 10x170=1700MH/S
Total power used for 25 months : 7,8KWH/hours , 187.2KWH/day , 5616KWH/months so 25x5616KWH for 25 months =
140400KWH ...
12cent/kwh power rate for 8 months :5616x8 = 44928KWH for summer months = 44928x0.12= 5391$ for 8 summer months power
8cent/kwh power rate for another 17 months : 5616x17 = 95472KWH for the remaining 17 months , = 95472x0.08 = 7637$ for 17 months power
So for 25 months I paid 13028$ for power to
run 10 Antminer E3 , that 10 miner provided me 1700MH/s hashing power .
As of today , You can do a calculation with 0.0345 USD/Day for 1 MHash/s , so with today prices my 10x E3 still earning me 0.0345 USDx1700/day = 58.65$ minus power usage 187.2KWHx0.08cents=14.976$ so the total what im makin as of today with those
10 antminer E3 is still not that bad
as of today , 12-10-2020 , 58.65$-14.976$=
43.67$/day profit after electricity If calculating back for the
25 months with today numbers , then this is how its look like :
43.67x30x25 the total money i made with my 10x E3 , if we do the math , then is 32755$ , I paid 8000$ for the 10 E3 25 months ago ,minus power usage, so the profit : 32755-13028-8000=
11727$ Profit for 25 months .
Thats on paper with today difficulty , price ... BUT THERE IS A VERY IMPORTAT THING ABOUT MY MINING PROFIT !!! I NEVER SOLD THOSE HARD EARNED ETH'S.
With today price/difficulty ... i can mine around 2.8-2.9 ETH / month
But dont forget ... in 2019 when the difficulty was way lower , actually half what we have now , i was able to mine 5.5-6 ETH/months . Even on this summer i was able to mine around 4-4.5 ETH/monts . Difficulty jumped like crazy from the end of July ! I still have all those hard earned ETH's from the past 25 months, so the real profit, is way much higher what i calculated here for you...
I hope i give you a very detailed answer
i Might opening another topic with all this information
