I would arbitrarily define individual as anybody with less than 0.1PH (100TH)=~100 S5 or ~20 Sp30-35. If you have more-you are a real business.
My prediction is not more than 10-15%, but I could be wrong and would appreciate pointers to an accurate estimate.
How many SP30-35 were produced? I remember seeing $28mil revenue for Spond.
With an average price of probably ~$4000 over lifetime of sales, this would be ~7000 machines or ~30 PH. Maybe 1/3 are individuals or 10PH.
Phil was posting estimate of S5 sales somewhere, but I could not locate it.
Antpool has ~20% (~80PH), but it is not necessarily all S5. Maybe 1/3-1/2 are individuals=26-40 PH or ~20K-33K machines which looks like an overestimate, so perhaps these numbers are too high. If estimates are correct, then ~36-50 PH are individuals (9-13% of the total hash) without counting S3.
Opinions?
I did two breakdowns of f2pool . They have 70ph at least twenty percent or 14ph is from 20 th or less.
The s-5 numbers I did are old from March 15000 minimum sold and paid with btc.
My guess for under twenty th miners is forty to eighty ph total of the network.
Ten to twenty percent of the 400ph in the network.
I am willing to do a breakdown of f2pool on weds as I know I will be tired after I drive from Virginia beach my Howell no home on Tuesday
