this is absolutely true - ProtonMail is located in Switzerland.
Are you using their hosting service as well?
I do not think it is bad in itself, but just thinking that you are more
secure makes you less secure.
The best way to get secure communication is to do it off-line. This means
1. use a device for encryption/decryption without internet connection
2. use a device for transfering messages with internet connection
Too many people died using same device for all shit in once.
For 99.99% of the people this is absolutely an overkill. It is enough to use
gpg and watch out what you write inside anyway.
