Maybe Petro is an utter bleepcoin and its prolly a bad investment but I will use it to send money to my girl there in Venezuela cos she's stuck there for two months already getting her papers done. Currently I'm using BTC for that but the rates on the street are total ripoff with 10-20% fees when buying or selling, they say that's because of hyperinflation and traders have to protect themselves with high fees. If Petro gets listed on any decent exchange I'll be able to send her money instantly without being robbed extra 20%, simply don't care what will be its price when buying cos she can use it there immediately, in a country hit by hyperinflation that's a blessing, as well as the fact that Venezuela would have fast and cheap international money transfers independent from the Central Bank. If the people in Venezuela start using Petro in theirs everyday activities, it would be a big victory for whole crypto world. I'm kinda confident that they will use it since many of them depend on help sent from friends and relatives living in other countries and Petro would be cheapest and fastest way to do that, also they are prolly one of the top crypto-educated nations atm.
If I was a bankster I would be very worried now because if that works out fine for Venezuela then some other countries would follow as well
