Well, as you describe it, it doesn't make too much sense, if at all (from our point of view), to keep running the node.
Our quick math says that you earn approximately 1.100 PRE per year. To reach the needed 4.000 PRE (from our understanding), you'll have to buy an additional 2.900 PRE per year. At the current price of $0.04651, that's something less than $135 USD you should "pour in." And all of it only if they don't change anything in the meantime, again.
Although we believe running a node can give you some feeling of satisfaction and fun, we don't find it worthwhile.
It seems like they figured out how to keep collecting fresh funds while giving a false feeling (to node runners) of some alleged free token "mining."
On the other hand, maybe there is some catch (hoping not some Catch-22) by which implementation you might be able to increase your daily earnings.
Just our 2 cents on the topic!
