It sounds like returns are highly variable and dependent on initial investment. I expect there has been an answer to this *somewhere* in the 50 or so pages of thread available here, but is there a sweet spot for investment? If so, what is it? And what is the current expected ROI?

Also I saw on another part of the site that doublebot is listed as "saturated"... does that mean it's about to close? or what's the deal?

Thanks in advance, sorry if this is common knowledge but I tried searching for an answer to no avail
