Even with the critical slant of applies to the gameplay of these "games" this article still ultimately neglects to describe the biggest problem with the "play to earn" aspect, which is that it fundamentally doesn't work.
The article describes the notional highs and lows of these tokens, but overlooks the fact that trading volume is far more important than a hypothetical trade price.
If one person buys one of these utterly useless tokens for 10 cents, that sets the price at 10 cents. But if I then try to cash out a thousand dollars of that same token, I'm probably not going to get a thousand dollars, because that requires there to be someone on the other side of great trade who thinks its actually worth putting a thousand dollars into this otherwise useless token.
To make matters worse, crypto prices are generally set by crypto trades. What I mean by that is that the person who bought one token for ten cents, actually didn't. They traded fifty BLOB tokens, notionally worth ten cents. What can you do with BLOB tokens? Nothing, they're worthless, they were made for a game that doesn't even exist anymore. The guy who owned those fifty BLOB tokens got them by trading a bunch of POOP tokens for them. Those are from a DAO that has since collapsed, they're worthless too. He bought those POOP tokens with a fraction of a DOGE coin, which he got from selling an airdropped Bad Monkey NFT that he was lucky enough to get one time (and even luckier to sell before the rug pull).
See the problem? It's all people trading Monopoly dollars for Game of Life dollars and arguing over the exchange rate. At no point did a real US dollar enter this process. So when you try to sell your BLOB tokens for real US dollars, no one is buying. The notion that people in developing nations will make a lining playing these games is a complete fantasy.
