Obviously the truth isn't absolutley necessary when dealing with Dinar. If it were why then do so many people believe the bunk that comes from the guru's? In this article he is talking about Central Banks holding Dinar in Reserve and I think that part is easily checked. In the end it is up to everyone to make a decision about Dinar. I've made money taking some advice from Sean Hyman (Soverign Investor) so I do trust most things, but I never ever go into an investment blindly and on the word of anyone.
Think about it, if everyone who wrote an article or gave investment advice had to be right 100% of time then no one would be investing in anything! BTW Turkey is a tradeable currency with a good economic outlook.
In the end like DB says do your own research. If you want to believe the hype and the pumpers, well go right ahead. My purpose for posting that article is to give you both sides of the coin.
