Does Switzerland use BTC?

Could you please elaborate on the question, "Does Switzerland use BTC?" I'm curious to know if Switzerland as a country officially recognizes or utilizes Bitcoin (BTC) in its financial system or economy? Are there any regulations or policies in place that govern the use of BTC in Switzerland? Also, how widely is BTC accepted as a payment method or form of currency within Switzerland? And what are the general attitudes and perspectives of the Swiss population towards the use of BTC? Thank you for clarifying this matter for me.
