Useful insights

Community and ecosystem growth

Crypto Angel Investors often highlight the importance of community when evaluating the potential of a crypto project. A strong, engaged community can fuel a project’s success. Here’s what to look for.

Measure the project’s community engagement

Platforms like Telegram, Discord, and Twitter are essential for assessing a project’s community. Look for a project that has an active, supportive community that engages with the developers and marketing team. Projects with loyal communities tend to fare better in the long run.
Check the ecosystem’s development

A growing ecosystem with third-party applications and services built around the project is a positive sign. Look at the number of developers building on the platform and whether the project encourages external contributions. This kind of organic growth indicates the project's potential for long-term adoption.
Look for governance and decentralization

Strong governance mechanisms, such as Decentralized Autonomous Organizations (DAOs), show that the community has a say in the project’s development. Projects with decentralized governance are often seen as more trustworthy and resilient, as they rely on the broader community rather than a centralized authority.
