Memes go through varying stages of popularity. Some burn fast and die off. Some go through a typical cycle. Some are simply useful or relevant and never die off. The point of the sub was to scout new meme formats and guess what kind of lifespan they'd have.

To add to that, a lot of it was emulating and poking fun at stock market trading, in this case the meme formats being a stock, and creating memes being "investing". For example, you could have a stereotype of some crazed investor yelling "BUY BUY BUY" as a meme format was becoming popular. It was silly fun and let people discuss meme trends in a novel way.
