Where can I buy cryptocurrencies in Switzerland?

As a cryptocurrency enthusiast, I'm wondering where the best places are to acquire various digital assets in Switzerland. With the increasing popularity of cryptocurrencies, I'm sure there are numerous options available, but I'm looking for recommendations on the most secure, reliable, and convenient platforms or exchanges to use. Are there any Swiss-based exchanges that offer a wide range of cryptocurrencies with competitive fees? Additionally, are there any physical locations or ATMs where I can purchase cryptocurrencies directly with cash? It would be great to have a comprehensive overview of the options available in Switzerland for buying cryptocurrencies.
