Is blockchain development worth it for startups?

I’ve been seeing more startups talk about building on blockchain, especially for things like smart contracts, secure transactions, and decentralized apps. The idea sounds interesting, but I’m wondering how realistic it is for an early stage startup.

From what I understand, the cost can vary depending on the complexity. A simple prototype might not be too expensive, but once you add things like security layers, smart contracts, and scalable infrastructure, the development effort can increase quickly.

I was reading about the process and key features startups usually consider when building blockchain products:

Curious what people here think. If you were launching a startup today, would you build on blockchain from the start or wait until the product grows?
