I'm looking to get into the market and I think 20-30m a day is an established small gold farm.
Anything from 31-74m per day is an average size.
Anything from 75-150m per day would be considered a large farm.
I haven't read of anyone doing more than that on a continuing basis though.
Goodluck on the RS Gold farm, I'm currently researching that market too.
You gonna use Osbot independent scripts or are u going completely private?
Your right tho this place is a great resource, even the years old content still helps provide insight into the community and Jagex's system.
