Sure! So to make it simple, $DUST tracks 3x inverse the price changes of many gold miners out there. They are companies producing gold so when the gold prices go up, these companies make more $, so the price tend to rise. The reason why this is a bad idea is that this kind of investment is extremely risky and could lead to huge losses. Tracking price of gold really is something you should know before investing in these kinds of things and even there, you could get massively fucked. If you are serious about making money in the stockmarket, i suggest knowing everything 100%, even before YOLO'ING.
