coups, endless lies, insults, mafias to any kind of physical, economical and psychological aggression you can imagine. Petro and the people around it are tougher than you can dream, i'm afraid.
For 20 years we've read and seen this insults on the mainstream media, social media and from the people parroting the media, billions have been spent to destroy Venezuela and Chavez... but the violence from the US and the wealthy opposition has been beaten over and over again, peacefully, while the popular support of chavismo has resisted. With the Petro we've seen the same intolerance and arrogance of the colonial brainwashed white men who think they know it all and actually know very little: that makes it even more clear to me that Petro will succeed.
To be fair, even normal size ICO often take far longer then expected from initial idea to full wheels on the ground working enterprise. Whats usually quicker is the token people can flip, but all the workings of an actual business behind that takes far longer.
I dont know this is the case with Petro but if it really is an ambitious project that will encompass an entire country then thats going to take far longer then a cardboard facade prop up ICO token. Its possible they are progressing and putting in the workings, people are speculating negatively and positively on this and PTR is not being traded ? which is frustrating for many no doubt, are they behind schedule officially yet or was it left open.
As far as adversities, I see every economy as challenging itself as naturally everyone wants to profit from exchange of value. Either the whole exchange system is positive and participants gain in some part on average or it throws itself off kilter and diminishes and alternatives once again take over.
