Trust me in 50 years from now or less there will be no government or organisation controlled currency anymore. At least not any that will be meaningfully valued.
Considering the average life expectency of the users accessing this forum, I dont think they are going to here anymore for that long time, I do hope to be proven wrong though. 
Rather I think we should spread the news so Bitcoin can be used as a secondary currency instead of PayPal/Payoneer, not primary which is not possible.
You mean secondary to fiat. I also feel this because the big companies that run the country are always going to go for fiat and not a crypto based system. Whether we will see future development in crypto and companies accepting crypto for use is a second topic to discuss about.Currently bitcoin should be kept to a trading asset status. If your country allows crypto, use it but also depending on who accepts it and who does not.
