Hm, i don't know but MBA took the easy way for PR'ing Blackcoin. OK, the keyword "blackcoin" will be on top when mentioned in an article on WSJ but "WHO" will google "blackcoin" anyway? IMO, just us the crypto guys and not my neighbor who looks for a new investment.
We need "Blackcoin" pop up in the first results when people google for "new investments" "forex alternatives" "bitcoin" "stocks alternative" etc. As a SEO guy, I would do it this way and yes, articles are 1 solution to that strategy. The other solution is getting "forex, bonds or stock alternative" articles on Blackcoin's main websites and SEO the hell out of them. Result: when people google "stock alternatives" there's a good chance they will notice Blackcoin.
