Title: If I mine bitcoin with S7 this is the calculation I get.Let me know its correct. Post by: murat6562 on June 25, 2016, 06:00:31 PM If I go with FACTS not any assumptions.
My hydro cost off peak time:8.7 cents Peak time:18 cents Mid peak time: 13.2 cents Average: 12 cents kwh Cad or 10 cents Usd s7 Hash Rate: 4730 ths s7 power consumptions 1293 kws pool fees: 2% bitcon price: 669 usd Block Reward:12.5 Bitcoin difficulty: 209453158595.38100 increase 8%-%10 every 11 days With all these facts EARNING is:weekly EARNING is 26.59 usd. http://www.coinwarz.com/calculators/bitcoin-mining-calculator/?h=4730.00&p=1300.00&pc=0.10&pf=2&d=209453158595.38100000&r=12.5&er=669&hc=0.00 When I multiply current difficulty with 8% and check next week EARNING is 7% less than this week EARNIING.I also calculated third week difficulty with same number and it gives me 7% decrease in EARNING every week. For example: current difficulty 209453158595.38100 x 1.08= 226209411283.0115 with this difficulty weekly EARNING is 24.62 usd .That profit is 7% less than first week EARNING (26.59usd) If all these calculations are correct AND difficulty is close to my calculations my EARNING AFTER 52 WEEKS IS 345.1534872 Minus power cost 1132usd. Only if bitcoin price will increase a lot and difficulty decrease s7 will profit. weekly EARNING EARNING after difficultY( 7% DECREASE EARNING EVERY WEEK) week 1 $26.59 $24.73 week 2 $26.59 $23.00 week 3 $26.59 $21.39 week 4 $26.59 $19.89 week 5 $26.59 $18.50 week 6 $26.59 $17.20 week 7 $26.59 $16.00 week 8 $26.59 $14.88 week 9 $26.59 $13.84 week 10 $26.59 $12.87 week 11 $26.59 $11.97 week 12 $26.59 $11.13 week 13 $26.59 $10.35 week 14 $26.59 $9.63 week 15 $26.59 $8.95 week 16 $26.59 $8.33 week 17 $26.59 $7.74 week 18 $26.59 $7.20 week 19 $26.59 $6.70 week 20 $26.59 $6.23 week 21 $26.59 $5.79 week 22 $26.59 $5.39 week 23 $26.59 $5.01 week 24 $26.59 $4.66 week 25 $26.59 $4.33 week 26 $26.59 $4.03 week 27 $26.59 $3.75 week 28 $26.59 $3.49 week 29 $26.59 $3.24 week 30 $26.59 $3.01 week 31 $26.59 $2.80 week 32 $26.59 $2.61 week 33 $26.59 $2.42 week 34 $26.59 $2.25 week 35 $26.59 $2.10 week 36 $26.59 $1.95 week 37 $26.59 $1.81 week 38 $26.59 $1.69 week 39 $26.59 $1.57 week 40 $26.59 $1.46 week 41 $26.59 $1.36 week 42 $26.59 $1.26 week 43 $26.59 $1.17 week 44 $26.59 $1.09 week 45 $26.59 $1.01 week 46 $26.59 $0.94 week 47 $26.59 $0.88 week 48 $26.59 $0.82 week 49 $26.59 $0.76 week 50 $26.59 $0.71 week 51 $26.59 $0.66 week 52 $26.59 $0.61 Title: Re: If I mine bitcoin with S7 this is the calculation I get.Let me know its correct. Post by: notlist3d on June 25, 2016, 06:15:22 PM My hydro cost off peak time:8.7 cents Peak time:18 cents Mid peak time: 13.2 cents Average: 12 cents kwh Cad or 10 cents Usd Hearing 18 cent's during peak time scares me personally. There are some good host's out there for 10 cent's or so. So I would really double check those numbers and make sure fee's/taxes are in them. Also is it variable where it moves up or down depending on how much electricity you use? Ok that being said about electricity having is coming very fast with 10 cent's a S7 really is not the machine for you if running around 10 cent's. You really need to look more twords the S9 it's efficiency will allow you to mine after having. I would suggest checking electric then doing ROI math again with a S9 instead of a S7. *Edit I also don't see having in your ROI math make sure it is included as it is coming soon. Title: Re: If I mine bitcoin with S7 this is the calculation I get.Let me know its correct. Post by: murat6562 on June 25, 2016, 06:31:22 PM Thanks.I would love to get s9 yet they are all sold out.Since Iam new to this yet I do understand more hashpower is more bitcoin .
There are lots of variables to watch for and I want to make sure Iam getting correct info from people who knows way more than me. I live in Kitchener Canada and electricity is expensive here. Its about 10cents Usd per hour if you get the average.Plus delivery, tax. Electricity Charges Period Time Cost Off-peak Weekdays 7 pm to 7 am Weekends & Holidays - all Day 8.7ȼ/kWh Mid-peak Weekdays 7 am to 11 am and 5 pm to 7pm 13.2ȼ/kWh On-peak Weekdays 11 am to 5 pm 18.0ȼ/kWh even with s9 that does not look very profitable with cost of electricity, bitcoin halving and increase in difficulty. I need more research and find a place for better electricity rates, and hopefully cost for s9 drop by then. Title: Re: If I mine bitcoin with S7 this is the calculation I get.Let me know its correct. Post by: philipma1957 on June 25, 2016, 06:38:20 PM your facts are so wrong it worries me.
A) how do you get to use 7% diff jumps as a fact? that is an assumption. why do you think diff will always be 7% B) you rewards are reduced from 25 to 12.5 coins. >>> you mention this which will alter difficulty >>>>> this you do not mention C) your s-7 will no longer earn a profit at a 12 cent a kwatt power price. and current coin and power prices. much sooner then you said like july 30th if your 7% and your coin price is correct. D) with all you got wrong one thing you got right is the s-7 should be a money loser for you. Basically due to power cost.

A) how do you get to use 7% diff jumps as a fact? that is an assumption. why do you think diff will always be 7% B) you totally ignore the ½ing which comes in about 16 days. rewards are reduced from 25 to 12.5 coins.

D) with all you got wrong one thing you got right is the s-7 should be a money loser for you. I guess you did not see. I used 12.5 bitcoin as reward after july 2016 for calculation of difficulty I was told 8%- 10% increase every 11 days.If you multiply todays difficulty x 10% you will see decrease in earning %7 .Thats how I find earning.You can create excel and calculate.Since Iam new and hear from others everyone says diffulty is min 5 max 20% What is the difficulty rate What do I need to correct Even tough Iam new I sense if you dont have free power and have not mining long time ago to save bitcoins mining will not profitable .

I did miss you had part of the ½ing the reward part correct. the diff numbers are very hard to know. as is price.

Post by: murat6562 on June 26, 2016, 04:08:04 PM I believe many small miners will stop because of cost of running of mining and not enough rewards in return.And miners who are big will take over their place.There wont place for small miners in near future.

Not really it just is that the S7 might not work after having for higher electricity priced users (those around 10 cent's espically higher). But there is the S9 with a HUGE jump in efficiency which allow many to keep mining after having that would not have been able to with S7. So a lot still will be able to but some will need to change to more efficient machines. We still don't know a lot on exact due to BTC value fluctuating.

Post by: Stedsm on June 27, 2016, 04:07:03 AM Mining might not work out for you as there are some more big miners coming in the markets which will alter the difficulty to a level no one would have thought of. So, it is possible that the calculations you have thought may turn out real, and you may end up in loss.
