You could choose to buy tokens during the run, when company's acquire the data, to acquire the required amount of tokens that are send out as incentive to those with the trackers running (as this is the data your selling), so lets say every company that requires the data, pays 6WHA per user, the wha-project pays 5WHA to the user and hold 1 for the data transition and development, rendering an incentive for the company to continue developping, increasing the userbase and eventually making it more interesting for company's and users to use the WHA-Project.
But hey, that is my 2 pennies

Before that moment, we have to get those tokens somewhere to reward the app users, to make them excited about using our app.
Yes, we can sell much more of the tokens, but how we will be super attractive to users?
We can put banners everywhere around people, telling them how awesome our app is and how precise is the analysis of their health parameters, we will get up to 5% of their attention.
Today, people are overloaded with ads from everywhere. So, being "just better" is not enough. Being different is another story.

On the other hand, investors, holding, let's say, 5-10% of all tokens can easily drop down exchange rates by putting all of them for sale.
