To my knowledge Switzerland is the best country for Cryptocurrency from continental Europe. but in addition to Switzerland of course there is another country that also receives Cryptocurrency well.
Switzerland has many great things but its many area's are heavily bugged down because of the politics in Bern. Lets say your entrepreneur in Zurich you own a bar before you even become profitable you will be doing a lot tax reporting to Bern and then I mean a lot. The crypto valley has potential but it is nothing more but a hype word right now, the real reality is really different if you experience the place. The hotspots for startups I would say is Germany I suggest searching around. The french are defiantly getting creative in the startup scene by buying up abandoned places.
This space can learn a lot from SV if it studies its history and adapts it to the crypto scene. Think about it the reason that people likes to live and work in SV is because it has that startup feel atmosphere. It has great media reporting on the many aspects that goes on. If someone said to me what is a huge problem in Silicon Valley now then its diversity Europe can tackle this in new ways, diversity can become a lot better but it want ever be perfect. Because of Europe's old history it has a lot of abandoned real estate around in its many countries where it can heavily cut down on expenses in the early startup days.
Because of Silicon Valleys rising costs what are they doing many are moving down to LA or Texas. In LA venture capital has gotten a lot better after its 10 year investment. In other states in the US places they will defiantly be a lot more cautious with throwing money around besides SV of course. Yes SV has been heavily overconfident of there dominance they have been sleeping quite a lot probably to long. The way they watched the world in the 90's and the early 2000's was like staying wired 24/7. If Europe really wants to start unleashing that decentralized startup magic it needs a startup culture and that does not exist yet, I would more say its in a massive testing phase now and saying to itself fuck is this really us can we do this. One thing that Europe needs is a massive gathering like the burning man, it needs to know that its has an identity in the tech scene.
