Beautiful! This reminds me of non-violent revolution topics way back when I was in college. The cafe remains legal for sure. They abide by the rules of not accepting Bitcoin since the country is considering it as such. But then it does not mean that they cannot advance what they think is a good thing. In a non-violent way, the cafe was thought of.
What if other business establishments name themselves after cryptocurrencies? Bitcoin Laundry Shop, or Ethereum Shopping Center, or perhaps Waves Outdoor Shop. Do you think this will hasten the legalization of crypto in your country?
