Small question. Since 2020, when I went to USA for work, I have in my house 1K USD in cash. It’s just sitting there and I think it will be more convienint to invest that money as I am not planning to go to the USA shortly. My question is, what is the best option to exchange USD to CHF in Swtizerland? In a bank, a currency exchange? I am from Vaud and I have an account in the BCV.
