I'm sure it will be in demand for the next 20 years. So I approve of your choice and wish you good luck!
But OP's degree is on the business side, wouldn't OP feel like it's a difficult thing to do because it's a totally different discipline and I think you should have some programming skills for this one to be able to make sense in all of this, if OP is determined, I guess that my negativity won't be a problem so I guess good luck to OP if he/she wants to take that course.
I get what you're saying, this specific Master's Degree is a little more technical, compared to Economics and Business. It probably requires some decent computer skills (Which I have) and at least some basic programming skills (I don't like programming).
The course outline is good, although you would have to ask yourself the question of whether you really like this or not.
Important. We need to involve ourselves with the thing that we enjoy doing and doing so will give us joy because we do and succeed in it with ease. So Op , this is left for you alone to know whether you like cryptocurrency and digital marketing/business. If you do then you should go all the way to grab the opportunity of a lucrative future venture. Is obvious that the crypto space is very young and whoever acquires a degree around it may be one of the earliest dominators and much talk about pioneers in the academic field even when you are gone to great beyond. If you happen to write books on it, you books will be highly sold across countries. I think it is a good field that you can venture into if you like it. Yes you already have a first degree that is still in the line of further showing the world about cryptocurrency and marketing/packaging it very well. Is a choice you need to made by yourself, I wish you good luck.
I do like Cryptocurrency and this whole digitalization, however, I'm not sure whether I could put that in perspective and use it as a career. Maybe I'll need to see for myself to get the right answer.
The course outline is good, although you would have to ask yourself the question of whether you really like this or not. Getting a Master’s degree isn’t tough, but you have to have $$$ to spare as it will cost you a lot. If you’re sure that you’re going to stay in cryptocurrencies and see yourself as a professional on the field in the future, go for it. Otherwise, there are tons of career paths you can take from your degree, and you just have to build your network, skills, and experiences from there.
This one in specific costs approximately 13.000 Euros, it's an extravagant amount, especially if you still haven't made up your mind on what exactly you want to do with your life.
