Yeah well it takes long to launch an ico and the dates may change that's obvious. But what makes me and other people think that it is scam is that they don't announce any delays, don't give out ANY detailes about the Petro. You always have to look for the information somewhere and can never be sure that this information is trustworthy.
I dont use the words scam or similar but failure is quite normal in possibilities, I dont know thats whats happened. Communication of events and advance in the protocol usage is going to be vital to part of establishing something of this depth and range.
Sometimes media exposure is the most important part of the success overall of a launch. Maybe they were blocked in this to some extent by sanctions and actually other parts are proceeding, I dont know and people assume the worst of course.
I had hoped the whole thing could be a positive for the people however unlikely that might appear to some its possible for inadvertent positives to occur, the magic of the blockchain however people might disagree on the technical details used it could have been a developing situation leading to secondary progress. At this point if they were having problems I would just hope the country is using crypto far more and stops trying to restrict the freedom of its people to adapt to difficulties they encounter just doing normal trade. Let them use crypto, it may be growth which is badly needed and technology can be a surprising positive resource, unclip the wings of those that might fly.
afaik it would be unique to have a crypto national currency so would be sad from that aspect to hear nothing about its progress
