Do you think cryptocurrencies can become the only transnational currency in the future ?

No ,I am not familiar with this because world is so much big and it has approximately more than 200 countries then how it is possible that cryptocurrency es can became the transnational currency in the future.

Mostly countries are democratic country then what happen if they regulate the cryptocurrency but the security should be high because anything problem arise or fraud things happen due to block chain then there will be responsibility of a government so it is very impossible that to make transnational currency in the future.

Cryptocurrency are banned in some countries due to government are not taking risks by regulating cryptocurrency because they also know that if they regulate then there would be so much big burden on them.and so to keep silence they banned the cryptocurrency in their nation.

I had only one point to think about Cryptocurrency can became the only trannational currency in the future is too have a proper block chain and good security as same as ethereum then it would be great for us
