Well I'd want to idle it for a set amount of time then be able to see how much I got. There's things that throw off the coin counts like triple chance and it seems like it isn't always the same amount regaardless, and unless I watched and counted how many things I killed I couldn't use that methd to get an accurate estimate of how much gold was made.
