Estcoin was a 2017 proposal for a national cryptocurrency tied to Estonia's e-residency program.[1][2][3][4][5] The plan was criticized by the European Central Bank President Mario Draghi, who said "no member state can introduce its own currency".[6] In 2018, the Estonian government clarified it was not planning to launch a national cryptocurrency and that it never planned to do so, but would plan to "explore various possibilities" for blockchain technology.[7]
