The initial idea of the project was to fund a big account to upvote the people in the community. In a way it's a holding token that you don't need to stake. In a way it can only gain in value (expressed in hive). It grows through curation and post rewards. Thanks to the delegations in hive, there is a nice leverage effect that allows the token to grow at a very fast rate. Delegators get paid weekly dividends in CTP that are financed with the curation rewards in H-E tokens.
We have a kind of market maker that replicates the theoretical value of the token on the market. There is normally a spread of around 4% so that the market maker can grow together with the token.
Hope I could answer your questions :-)
