Would be interesting to watch how Dash does in this situation and especially post launch of Petro in November.
So far, Dash has been adopted by quite a few Venezuelan merchants (more than 50% of Dash accepting merchants are from Venezuela; https://twitter.com/StayDashy/status/1048678327693856768). And to top it all, there are allegations of Petro being a Dash lookalike.
Personally, I don't think a state-backed (in this case, state enforced) crypto like Petro will do well anywhere outside the country. Venezuela had offered a 30% discount to India if they purchase oil with crypto but they declined the offer (https://oilprice.com/Energy/Energy-General/India-Wont-Pay-For-Venezuelan-Oil-With-Petro-Cryptocurrency.html).
