Let's say I have 6 rx 480 mines ETHEREUM at 28 Mh/s. 115w per card total 690w. Cost per KW/h is $0.12.
Current diff is 259 T. Current Eth price is $44,27.
Here is the Ethereum difficulty chart(T) with percentages;
2016;
May(34) to June(42) ---> +%23
June(42) to July(55) ---> +%30
July(55) to Aug(54) ---> -%2
Aug(54) to Sep(70) ---> +%29
Sep(70) to Oct(76) ---> +%8,5
Oct(76) to Nov(73) ---> -%4
Nov(73) to Dec(70) ---> -%4
Dec(70) to Jan(79) ---> +%12,8
2017;
Jan(79) to Feb(111) ---> +%40
Feb(111) to Mar(152) ---> +%37
Mar(152) to Apr(239) ---> +%57
Now based on this 12 month difficulty chart, I'm predicting %29,66 increase at difficulty every month.
Here is the monthly revenue chart for my six card;
Here is my calculation about how much I'm going to make and lose;
Here is my question comes;
1- Based on this calculation if I invest total $3.000 for everything, is that mean I will get $1790 net profit for the first year?
2- Did I included the difficulty in a correct way? Is my calculations right?
3- Why Ethereum difficulty jumped from 79 to 239 in just three months?
you only need to understand that price drives difficulty.
eth was trading under 10 usd .
eth is trading over 40 usd.
so difficulty went upwards.
All your longterm numbers are a waste of time.
Since you have no idea what coin price will be.
When trying to figure if you will make money do not go beyond 60 days. So you can not possibly accurately predict long term/
so see the price change below.
