May I ask, to whom does “We” refer to? and are you an official representative from the Venezuelan government?

If yes, this mean that Petro is built based on NEM blockchain and the value is backed by oil reserves. So, how can I calculate the value then? Is 1 Petro is equivalent to 1 oil barrel?

How can I buy Petro and what is the three symbol characters of this currency? I found PetroDollar (XPD) in coinmarketcap.com. Is it the same currency or not?

Thanks in advanced.
