Do note that the values expected in the White Paper are 30 times higher than actual results.

Sadly, language is art, not science or engineering. I tried to address that by noting that stake weighting is relevant to both investment and profiteering. I don't actually consider financial manipulation of rewards speculation, but profiteering. Speculation is just bad investing IMHO. Warren Buffet is not speculating when he buys stake in a company, although the ROI is a result of an increase in the price of the asset. He generally sets out to improve the business to produce that increase in value.

Speculators are folks that just watch Warren Buffet and buy what he buys. They just expect an increase in price without doing anything to improve the business. However, doing so puts upwards pressure on the price, so it's not profiteering.

Sorry if my writing doesn't convey well the differences in methodology and impact the practices under discussion have. I don't know of any better words for the job.
