PalNet is a bit over a week old and the composition of stakeholders is still very fluid, with significant differences from a day to the next.
I'm not going to through at you a bunch of numbers, mainly because I think we are going to see major changes as the interface becomes more adopted and more time will pass.
What is best for you to understand is that you've got to separate yourself from what you learned on steemit.com about how the Steem economics works, about what whales and minnows are, about ways to earn STEEM etc.
Things are set up in a different way on PalNet and there is no direct correlation to how things happen on Steem.
I've seen people saying they don't understand how it all works, or who needed time to get it.
As everything new, people are picking it up at different paces. Or they might give up on trying, if they feel it's too damn complicated for them.
Don't panic if you don't get it! There are others like you. And when the news about PalNet snowballs and starts to be explained in different ways, by different people, with different backgrounds, it will become easier.
In the meantime, PalNet will change rapidly now at first. What is true today may be (slightly) changed next week. So expect that.
I remember when I joined Steem it took me about two weeks to understand pretty much anything. From mark down to reward pool, to SBD, payout window, witnesses etc.
You are in a much better position as a Steem user to understand PalNet than a new user to understand Steem. But still there is a learning curve. Or at least an adjusting curve.
First payouts started to come. But that's not the only way to get PALcoins. At 50% curation rewards, this is an interesting option, but probably only after the next PalNet release for people with small stakes. You can mine them or you can be active in PAL discord for them, for example:
Be a PAL and Steem on! ;)
