The move to market prices was always better, there is only 5 million Actifit in circulation that's a very small amount it won't take much HIVE to eat through the order book, you'll be surprised at how quickly you can shoot up the token value and marketcap. Yes you would need some outside investment but LYMPHO does the same thing as actiit on ETH and it's not been great and they had an ICO to raise funds, they currently at a market cap of $1,588,304 USD so I think there is appetite to invest in a project of this kind

As for the ads I'd say they can either make it opt-in or make it that you need to stake a certain amount lets say for argument's sake 20 000 tokens and you don't see ads, that gives you an incentive to hold the price up and not dump tokens but also earns revenue from those not staking and wanting to dump evening out demand
