Useful insights

Analyze the use case and real-world application

When evaluating crypto projects, another critical factor is the project’s real-world use case. Top investors and developers always look for meaningful applications that solve real problems.

Identify the problem it solves

One key lesson from experienced Crypto developers like Vitalik Buterin is that a project must solve a real-world problem or significantly improve an existing process. Assess if the project addresses a clear need in industries like finance, supply chain, healthcare, or decentralized applications.
Assess market demand

Crypto Angel Investors often focus on the market demand for the project's solution. If the project serves a niche with little competition or improves existing technology in a meaningful way, it has a greater chance of success. Conduct your research to evaluate whether the project's target market is growing and scalable.
Check for partnerships and adoption

A project that has established partnerships with reputable companies or institutions is generally seen as more credible. Look for announcements of collaborations or endorsements by industry leaders, as these can indicate trust in the project’s potential.
