ELI5: Can someone explain to me what FOREX trading is? And why is it gaining a lot of popularity right now?

EDIT: I am seeing a lot of posts on Instagram and Facebook from people I got to university with. Apparently they are making money out of FOREX and there are a lot of people "recruiting" freshmen students to get into this. What is this exactly? , and is it worth getting into this?

It is trading currencies... FOREX stands for Foreign Exchange. Due to the drop in oil supplies and slowdown in China, currencies have been more volatile the past few months, which means more opportunity to make money from trading currencies (if you know what you're doing). But it's complex and there are many people who've been doing it exclusively for many years... it's not something you can just dabble in with no knowledge and expect to do well.
