You're right about that. Not many coins are PoW nowadays. The market is full of shitcoins and tokens based on PoS. If this keeps up, the industry might become heavily-centralized. It goes against the principles of crypto/Blockchain tech. Consider how Bitcoin hasn't switched to a new consensus algorithm, despite many people criticizing its "high-energy" consumption. The energy "wasted" is being put to good use as it makes the network much more decentralized and censorship-resistant.  I'm glad Mooncoin is still a PoW coin, or it would've been a goner.  Hopefully, a country like El Salvador would open up to Mooncoin as PoW-based cryptocurrencies become extremely rare in the future.
