Up until recently, blockspace was expensive and slow. In the last year, that's no longer the case. Also embedded wallets / smart contract wallets / Passkeys will continue to make it straightforward to make any crypto app aware. On-ramp APIs are also much better (but still the largest point of friction for a pure consumer app).

It's 2024 — the consumer web is 30 years old and the modern smartphone era is almost 20 years old. Internet software is a mature industry. Obvious ideas (regardless of whether they involve crypto) are solved.

So if it's an existing idea + crypto, you usually getting, at best, a 10% improvement. It's not a 10x improvement. And if it's not 10x, you won't really get people many people to switch. (And for the last 2 or so years, crypto's brand association has been more negative, so if anything it's made a product overall worse from growth standpoint.)
