Estcoin
Estcoin is a mooted national cryptocurrency, devised by the Government of Estonia in August 2017. In June 2018, amid criticism from banking authorities, Estcoin's plans were revised to no longer peg its value to the euro, nor for it to be a national cryptocurrency, but that Estonia would plans to “explore various possibilities” for blockchain technology. As it will be restricted to individuals within the Estonia e-Residency program, it cannot be exchanged freely and thus technically doesn't qualify as a cryptocurrency.
