Bitcoin is money, and blockchain is good enough for the simple use case of money, for more than that is terrible and ineffective. All other "projects" either are scams or bad ideias thinking it's good to put everything on blockchain, from social media to games. Nostr is a good example that you don't need blockchains or tokens to be decentralized. Most of everything else is just gambling on tokens that are all going to zero against bitcoin, including ethereum the mother of all shipcoins.
