Any project like this takes time to get going word of mouth and advertising can only spread so fast not to mention when it comes to exchange the best thing for building trust is time and efficiency so over time more and more people will adapt
I agree with you. Word of mouth is very important for any project. But in this kind of projects, its highly essential. But I am sure Bittwatt team is aware of this and will work on it to make it successful.
What I see is that, team is not doing enough social media marketing. I know ICO is finished but if BittWatt team wants to promote their exchange/energy trading platform then they still need to do lot of marketing.
