I am a 18 year old living in Lucerne and have a lot of accounts. I have one at Luzerner Kantonalbank (cuz my parents made it for me) with no credit card but with a stucard. I also have a Zak account with their mastercard and a revolut account, for traveling and paying for foreign transactions (Zak Mastercard has a fee of 1.25% for these).
I also have 900fr invested using Trading212 (now worth about 1k)
I was interested in the Viva Bank accounts of Credit Suisse as they offer great interest (for Switzerland at least) and also cheap cinema and a 50fr sign-up bonus.
Can one person have too many bank accoutns here, as long as they are not some expensive account?
