The most interesting question at the moment to me is: "What can only be built with crypto?"
These are novel user experiences that are unlocked by crypto, which aren't possible on traditional rails.
Examples of "Only with crypto":
@cryptothegame_ could have only bootstrapped its prize pool so quickly & disbursed payments to players around the world on crypto rails
@farcaster_xyz Frames passes a message containing users’ FIDs that can be linked to ETH addresses, enabling developers to personalize the experience for users regardless of where they’re interacting with the app.
DEPIN networks that bootstrap one side of the network using tokens before full marketplace utility is present (e.g.
@Hivemapper @DIMO_Network @helium & many others)
@shibuyaxyz @TallyLabsNFT user-directed media with economic skin-in-the-game
Wallet-aware e-commerce, like
@coinbase's Penny Hat which had a steep tokengated discount
coinbaseshop.com/products/pe…
This list is rapidly growing each day. What else can only be built with crypto?
