Cardano dApps need sustainable revenue to survive and the single-sale model (token sales or NFTs) doesn't work because it front-loads value extraction but back-loads responsibility.
When a team does a single-sale, they receive the capital up front and the buyers then have to hope the token appreciates over time.
There is a heavy reliance on trust and narratives.
Because the team has already made their money, focus often becomes about:
→ secondary market volume
→ floor maintenance
→ marketing cycles
→ listings
Rather than
→ product market fit
→ revenue
→ real product usage
In many cases, appreciation of the token becomes the product and this takes focus away from actual utility.
If the primary monetization mechanism is the initial sale, early buyers depend on later buyers paying more and it traps even good projects because there was never an actual economic engine and value depends on market sentiment.
Recurring revenue and ongoing usage are really the only way for a project to achieve real sustainability in this space.
Nucast has contributed an open-source subscriptions and micropayments product that projects can use to charge a recurring fee for goods and services.
The infra is there, it's up for projects to use it!
