You make a physical representation of something digital which also changed denomination quite often the last 10 years?
What do I do with it?
I mean first of I need to check if the value is on that note so I need a smartphone. Now I have a smartphone why do I need a note?
The only useful thing would be if I as the giver don't have a smartphone but than I also need to give away a printed object. How cheap can someone print something like this?
Now Bitcoin makes even more garbage?!
