If you're in a third world country, you likely don't have access to robust, transparent local stock markets. Whatever exchanges might exist tend to be rife with scammy companies, insider trading and poor regulation. If you want to invest in, say, the US stock market, you'd have to jump through a ton of hoops or have a ton of money, essentially locking out all but the wealthiest.
These crypto "stocks" essentially allow anyone living anywhere to "invest" in top-tier stocks like AAPL.
I don't see any reason why you'd buy these crypto stocks if you're living in the US. But if you're living in Somalia or Madagascar? Hell yes.
Again, all the crypto criticism is very myopic and first world. HN needs to step out of that POV to understand the value. Decentralized, global markets don't benefit first world citizens, but they definitely level the playing field for us third worlders.
