I used to take 200 euros every few weeks at the ATM when I lived in Germany, and had to carry around min. 30 euros to be sure I could run errands on my way home or whatever. Honestly I didn't feel comfortable taking all these bank notes from the atm in the middle of other people, and carrying so much cash all the time. Had I been robbed, or had I lost it, it was simply gone. A card fraud you can contest (and hopefully be covered if your bank and card insurance is good enough)

Now that I've left ? Rarely have more than 10 euros in my pocket, can take 20 euros at ATM and not give a shit about fees. I can pay with my card everywhere.
