It is more of a CBDC they are creating. Just having a block chain doesn't make any currency a cryptocurrency. The main feature of a cryptocurrency is its anonymity and decentralization. The Swiss currency is definitely not going to be decentralized. So it's a government issued digital currency you can say.
Criptocurrency is something different so let's not confused between Fiat and cryptocurrency. No matter what Swiss government is doing, they won't be creating a cryptocurrency even if they like to call it a cryptocurrency.
