Have you been following the Ethereum hacks? I can already see it, let’s hardfork to give people back their estcoins LOL, huh you mean to say that I now have 2 estcoins? Yeah you guys do, but not the people who got hacked! ERC20 tokens (estcoins) have tx costs above $0,30 per/tx, pretty expensive when your use to free with the banks for national tx’s.
It doesn’t make sense for rich/wealthy countries to do this, because they’ll get their trillion dollars hacked and airdropped to everybody in the world.
For these countries it does make sense to have an own cryptocurrency/ico. Even print enough to pay your debt with the IMF, with an ICO of a million $, your token is good enough to show up on coinmarketcap and exchanges Some poor countries can maybe even back their tokens with their natural resources
Gnosis can become a central bank, they hold close to 9M Gnosis tokens that they can lend to poor countries
