Crypto projects are highly dependent on their following, and you need to make sure you receive feedback from them, and they get to contribute to the project development at least in a small way.
Press: Do You Even Need It?
The short answer is: yes, you do. Here's a long answer: even though crypto is an online business, so are many of mainstream and fintech outlets. Some evolved from their "paper phase" and entered the digital era, others developed on their own with the spread of Internet. But to promote your project and to show the potential investors that you mean business you need to get involved with popular media like Bloomberg and Forbes, as well as with crypto related once, like Cointelegraph and CCN.
Note: if you struggle to find a starting point, you can compose one-page proposal with your initiative and send it to editors or writers, attaching your white paper if you want to. However, they get such proposals every day, so make sure your message is brief and highly informative.
