I think they really see the benefits of not just using blockchain, but the what it can bring to a small nation just like them. As @figmentofmyass, superpower countries are very timid and less enthusiastic because, they're financially stable as compare to 2nd or 3rd world countries. But what we do like about them is that they really spearheaded it for some time now that's why crypto related projects, exchanges are now moving to them.
We have all seen for a while now, how some of the exchanges alone have been making a huge amount of revenue daily and imagining some other blockchain businesses that will always tend to move to a more cryptocurrency or blockchain friendly zone in the long run will bring to their economy. I guess they are so smart to take the bold step than being a laggard in the long run, which is what most other countries will end up as.
