How can it possibly mean something else? To say so is deception as you cannot buy 3B O/S shares, hold them and still trade 15B shares overall.
Is there a portion of the 3B sitting in people's accounts for the long term? No doubt, but you can't have consistently 500M+ shares traded daily if people are buying and holding, unless of course, Koos is putting 500M new shares into the market daily. So, I guess you are right, it could mean something else - huge dilution never seen before, but since that has not been declared by the company, I give him the benefit of the doubt.
