For anyone interested in a very current topic, it might be good to look at the following text about the Runes protocol, which I pasted from the source below:
I'm not sure creating a new fungible token protocol for Bitcoin is a good idea. Fungible tokens are 99.9% scams and memes. However, they don't appear to be going away any time soon, similar to the way in which casinos don't appear to be going away any time soon. Creating a good fungible token protocol for Bitcoin might bring significant transaction fee revenue, developer mindshare, and users to Bitcoin. Additionally, if this protocol had a small on-chain footprint and encouraged responsible UTXO management, it might serve as harm reduction compared to existing protocols. At least one of which, BRC-20, is already quite popular, and has the undesirable consequence of UTXO proliferation.
