Proper equation for Calculating numbers of Scrypt Based Coins per day...

[ckoeber]

Hello,

I am trying to do an Excel spreadsheet of the amount of coins generated in mining an SCRYPT based coin per day.

Here is what I have so far, based on what I pulled from various online sources:

Number of Coins in Block Reward, which I will call N, divided by the following:

Difficulty multiplied by two (2) to the power of thirty two (32)

OR

Diff*2^32 : lets call that D

This entire amount divided by the hash rate, which I will call H

so D/H so far.

Divide this entire amount by 3600 (or the minutes in the day?) which I will call M.

so now (D/H) / M

Now take that final amount and divide it by the number of hours in the day, or 24 which I will shorten to day.

so now ((D/H) / M) / Day

So that leads me to the following equation (using my abbreviations above).

N / (((D/H) / M) / Day)

However, this calculation is off as when I plug the numbers in the final amount is incorrect.

Can anyone help me with getting the correct equation? Also if you can break down what is divided by what that would be great.

I am not the best at math but I try

So anyone know where my formula is off above?

Thank you again for your time.

Thank you again for your time.

I don't have time to really dig into this right now, but one thing I see is that I don't think you're accounting for block-time anywhere in your current formula?  Coins that might have the same difficulty and block rewards would still vary, possibly greatly, depending on their average block time, so I think you at least need to include that value in your formula.

edit:  for starters - (mins_per_day / block_time_in_mins ) * block_reward = total_coins_per_day

so for Litecoin ( 1440 / 2.5 ) * 50 = 28,800

Hope this helps, at least a little...

That's a good point; I will research that but if anyone has pointers in that direction I am all ears

Formula I was using:
Coins mined per day = BLOCK_REWARD/(DIFFICULTY*2^32/HASHRATE/3600/24)

So for DOGE:
Block reward = 250000
Dif = 1689.09740750
Hashrate = 1000000 (1 MH/s)
Coins per day = 250000/(1689.09740750*4294967296/1000000/3600/24) = ~2977

And to check it if it's right...

So for DOGE:
Block reward = 250000
Dif = 1689.09740750
Hashrate = 1000000 (1 MH/S)
Coins per day = 250000/(1689.09740750*4294967296/1000000/3600/24) = ~2977

Nice... How accurate does this seem to be vs what you are able to mine?

Also, it might be worth including any required pool fees if trying to do a full compare between coins and pools where you would mine them.

Thank you so much, my question is where are the divisions happening above?

For example, is 2^32 being divided by 1000000 or is it (Diff*2^32)/1000000?

I am not clear what is being divided by what based on what you wrote.

It's just estimate. Pools can be lucky/unlucky, difficulty changes all the time.

It's the basic math, start from multiplying difficulty by (2^32), then divide by 1000000 etc
Don't think I made any mistake, put it in google and you will get the same result (edit: oh right, and it tells you how it's done).

Thank you. Using Excel is weird sometime and you have to specify what is being divided by what.

I need to brush up on how to read math in single line form

I am used to it in how you would read it in math textbooks...
