Switzerland and European nations are already friendly with Bitcoin so El Salvador don't change anything in Switzerland with this action.
It is only kind of noise on media that is good generally and for Bitcoin adoption too but I disagree if saying like El Salvador and their Embassy in Switzerland are changing a whole Bitcoin adoption there.
It's not just the Bitcoin adoption in El- Salvador but it's also some other countries accepting Bitcoins on their own , I recently went to Budapest, Hungary and there was an amazing Bitcoin cafe!!
Blockchain is future of human civilization and Bitcoin is a king in blockchain industry so it is normal to see it almost everywhere.
Did that Bitcoin cafe accept their payments in both Bitcoin mainnet and Bitcoin Lightning Network?
