I think this is a follow-up to the news about El-Savador which shocked the world with its success in using Bitcoin as legal payment in its country. Therefore, there are starting to be countries that are opening up to accepting Bitcoin as payment in their country.
Apart from providing financial freedom in a country, the use of Bitcoin as payment has become a bright spot for Bitcoin becoming better known to all levels of society. if that continues, bitcoin will rank first in the world's assets and could eventually beat gold. even though it is rumored that bitcoin is digital gold and deserves to be put on par with current world assets.
Switzerland is I believe one of the countries that is open to crypto market even in the early stages of its inception. So it is no surprise that one of its cities will officially accept btc in their payment/financial transactions. Only a matter of time that other cities will follow thru.
If btc will just be like any regular fiat to be included in the payment sector, this will further boost its popularity and so its demand. Given that it has fixed supply, we already know where the price is heading to. People will also discard the idea that it is only being used for illegal transactions over the net, which sadly, many still have that kind of notion towards this digital currency.
