weird. i'm european, live in europe, only use credit cards. either visa or amex. they offer better protection when buying something, protection against scammers, plus added benefits (from travel to cashback etc). it also contributes to my credit score.
if anything i think europe is actually craving a lot more credit, see klarna as a good example.
But using a credit card like MasterCard or VISA in Denmark usually incurs a fee with most merchants.
As for protection, I think you still have months to report fraud. Although you should always report it as soon as discovered.
2008 changes a few things and somehow Debit Card in US caught on. Credit Card in EUR increased as well. I think Debit Card now represent something like 40%+ of transaction in US. Credit Card in EUR is still comparatively small, but much larger than pre 2010s mostly due to company spending.
IMHO credit cards and the systems around them are a remnant of the past. The US just hasn't caught up with the rest of the world yet.
