Wait, if we do 75/25 split then we are adding another barrier to manual curation. I think maybe we should go for 60/40 split. I think the best solution to 'token distribution' problem is to create and promote curation projects. Btw, 50/50 split is the reason why anyone would want to stake their PoB, otherwise there would be no reason. What I am trying to say here is 'staking' will be lucrative if people get more rewards for curation.
On Hive, the distribution of rewards is getting wider day by day, thanks to the several curation initiatives that are working day and night to support underrated authors.
These projects on PoB can provide returns to delegators in Liquid PoB. I am sure many would delegate to bootstrap. We can rely on a group of people rather than one person. For a solo stakeholder, it gets tough to distribute rewards manually to a wider range of people every day. It's humanly impossible to expect them to go all in. Whereas a group that is fully dedicated to doing this on a 24-hour basis will perform better. This can also be coupled with curation trails to make it more interesting and efficient.
In short, these projects can pay curators, pay delegators and distribute rewards in a decentralized manner. WIN WIN WIN for everyone! We need to create a self-serving economy where everyone is incentivized.
