Looks nice, at least at first. Maybe you could add a demo feature to let you experience the site before signing up.
How did you choose the 25 coins?, by market cap?, availability of block explorers?, or just at random?
Great suggestion, thanks for the feedback!
Yes, we chose the 25 coins first by market cap and second by ease of integration.
Our desire was to keep the interface clean. Behind the scenes we have hundreds of integrated coins and thought it would be best to get user feedback before fully pushing all coins into production.
