For sake of example, I did just make a post that would show you how to do a proper investor call. It's located HERE for you to take a peak at. Take notice that I go into talking about a particular frontend, what it's based on (steemit), mention other services that use it, compare it to the social media giants, point out the social media giants are actually failing and why it's happening, then tell them out SBD a year ago vs SBD price now as well as getting them to think about it's prospect of the future if they're to invest early rather than waiting until it's already spiked high.

The article is targeted to not only attract new users (content creators) from the various social media platforms, but also targeting potential investors at the same time.

Hope this helps when trying to explain in your upcoming contest. (And no I'm not trying to do a pre-emptive entry, best example is by actual example rather than explanation).
