Let me be clear about this. Petro is a scam. I see a lot of comments seeing this as an opportunity and a good thing for cryptocurrencies but all of you are missinformed. Right now, we have zero chance to invest in cryptocurrencies because we have zero freedom in our economic choices.
So please stop telling lies about what you don´t know, this is just goverment propaganda based in fake information. This is bad for the cryptocurrencies in general, petro value is less than zero because is just a scam and in reality, there are just a communist reform made to take control over every private asset in the country. 
By the way, things like this are making steemit a big steaming pile of shit, stupid bad content made trending by the use of bid bots. You should be ashamed.
