I don't think this is anything new that is really surprising. Long before I read the news you quoted, I had read online about several other top universities also offering some kind of courses, master's degrees, or certification programs. I really don't remember when and where I last read it, but given the continuous development of technology and the crypto industry, many universities will be actively involved in offering programs related to it.
You may be right, the master's degree program is the first of its kind in Spain, but in other countries it may have existed before. However, the initiative of the University should be appreciated because with it the crypto industry is getting more famous and getting more attention from young man as the next generation.
What's new is that they are teaching specifically about Bitcoin and how things around Bitcoin are done, such as creating and using wallets, how mining works, and how one can set up a mining rig, etc. There are too many institutions around the world who are teaching things related to this industry, but they are mostly focusing on blockchain, and that is a different thing than this course because it isn't teaching students about the blockchain and how to create a blockchain, but it's focusing only on Bitcoin which is a great thing.
I believe people from that city or country will surely enrol in this degree because it can be very useful for them, but there is one concern, it would have been better if it wasn't a degree but some separate course that anyone could attend to get the knowledge instead of spending so much time and getting their degrees in this major because one can learn those things even in a course without having to pursue a degree.
