Already having a product that works is a great indicator that they're serious about their project. This also creates trust with possible investors. There are a lot of ICOs around these days and many of them cannot deliver what they promised.
This is what we need to make crypto revolutionary. Integrate decentralised crypto into the real world! This way we will empower ourselves more, take back the control over our own wealth, and work together to provide great value to one another.
Steem on!
