As a CPA, I would say my proof is in the financial statements. How long has South Africa been a topic on here and I see no sales there. Where are the sales for South America? I know it takes a little time but there has been a decent amount of time passing.
Additionally, if these international markets were going to be so great, shares would not be selling for .00005. The good thing for BW is that he can tout the international market but they are hard for people doing DD to prove or disprove.
