Bitcoin is the best money we’ve got. If you want digital tokens then sats are the best we’ve come up with. If you want a decentralized app for whatever reason (e.g. censorship resistance) then you don’t need a blockchain for that.
P2P is all you need and for that we have Nostr, tor, etc. Make your app open source and if it’s needed then people will run it decentralized.
Decentralized finance is mostly a gimmick. Imagine borrowing money to buy a home and then years later you quit making payments. A DeFi token protocol can’t physically repossess the home and you don’t need it to facilitate communication or market making.
Don’t fall for shitcoins folks!
