Good for them. But I'm not sure why we necessarily need to connect everything about Information Technology and Computer Science to "cryptocurrency investments". Especially noting that most "cryptocurrency investments" in general are a bad idea especially for the inexperienced trader/investor.
Simply because globalization is an off shoot of modernity. You don't want to have difficulties in global scheme and trade especially for allied nations, maybe that could be a reason. Because if we view countries recently adopting digital system, they are almost countries with trade affiliations. At least for now, we can relate the reason with that.
