I keep seeing this metric everywhere, it's irrelevant, $GME became a meme stock, people are joining the sub to check out the fun, not to invest. Max 1% of them are really investing anything of value.
Cannot confirm, I joined to watch things to eventually buy, and I bought. I never bothered with stocks before. I also know many like me, in my real life circle, who did the same. A good chunk of WSB holds GME, is my estimate.
