You could call Ğ1 a cryptocurrency if you’d like to, as the blockchain is actually based on cryptography.

But it would be to forget that cryptography is neither the privilege of the blockchain nor the one of the currencies that the mainstream medias will call cryptocurrency.

Cryptography is used to secure every digital transaction, in euros, dollars or any other currency.

A free currency could as well be managed with paper or clay tablets. It would be less practical and would probably require a central body.
