Many cryptocurrencies are currently being developed like bitcoin, dogecoin, dashcoin , litecoin etc. Just like now we have different paper currencies for different countries. It is possible that in the future each country will decide or develop its own cryptocurrency?. What do you think about this? Please share your views.
It is possible, but people will still lose trust in a government based cryptocurrency. Because it is likely that the government will retain a tight hold on their cryptocurrency, however decentralized they may claim it to be.
Altcoins might not last long because most of them are pump and dumps. Bitcoin I believe will be used as currency in the future.
