The only problem with caracaschronicles.com is that it's opposition garbage, basically publishing a mix of propaganda, fake news and conspiracy theories in English, for the international gullible consumer.
Read the article, evaluate its arguments. By discounting from the outset all information and reflection made available by sources associated with the opposition and by international mainstream media your are insulating yourself from rational reasoning.
Learn how media works. Follow the money. I read everything and that's irrelevant as I said in previous posts. But you can keep repeating this "backing" thing over and over again, it's fine.
The Petro is potentially valuable for tons of other reasons too, even if it wasn't backed at all.
