I bet when you walk in any city in netherlands and ask 100 random people if they know about gulden, not even 5 will know about the 'Digital currency' one
Not yet I guess. Most people you ask will probably know BitCoin, but how many of them actually understand what it is? Knowing a name is just one thing, but knowing how something works or how it is meant to be used is worth a lot more. Actual use cases will bring a true perspective to users on how to actually handle crypto coins. My guess is that a 'local' and/or country specific crypto currency could work well.
