As much as I liked the first crypto stamp... with the 2.0 things went downhill. Quality wasn't en par (paper only) and their obvious cash-grab tactics made them become less and less attractive to me and many (crypto) stamp collectors I know.
It's kind of sad to see, the initial idea was cool and with some real innovation and good designers this could have turned into an amazing yearly series.
When I look at this CS 5.0 all I see is an ugly design with probably way too high of a mintage.
Agree with you....I just do not like QR codes taking up so much space on the front of the space....if only they were smaller and
lees intrusive...plus of course a much better design it would help like these created by AI!

These ideas/examples do look great, but are not scannable in this format.
You could either extend the QR-code algorithm to allow fancy designs to be scanable - problem is, older software will not be compatible.
Or you could integrate the QR code more intelligently into the full design but it would still keep its typical look.
Regarding the crypto stamp from Austria: The first one was designed by an artist. Still a matter of taste of course, but from 2.0 on it was just some designer's work, missing the heart of CS1.0 - generic design combined with this massive production for such a tiny country. And imho the design got even worse after that.
The Lichtenstein and Swiss CS at least had some good looks to them in comparison. Just my personal taste, though.
