How Hard Is It to Learn Dutch?

It is spoken by most of the people living in the Netherlands, and a majority of Belgians. Additionally, it is the second language to around 5 million people. But, despite the conquering activities of the colonial Dutch, the language has not gained much traction outside of Europe. The exception to that could be South Africa, where Dutch was widely spoken and then evolved into Afrikaans – a very closely related sister language whose speakers are able to understand (and be understood by the) Dutch.
