Honestly, I feel this is one of Incognito’s biggest issues with nodes. Not the earning mechanism, but the unstaking mechanism.
The reason I am worried about my non-earning node is not because it isn’t earning. That sucks, but from the very beginning I understood that selection is random. So I felt okay spending nearly $400 on the node, knowing that it might not pay for itself quickly, but should repay me slowly over time. What I didn’t think about is how unstaking can also take a long time, since unstaking is tied to earning.
If a node is not earning, it will not unstake until it does start earning. This means 1750 prv is locked up until the next time you get lucky enough to earn. Right now, at market value, 1750 prv is worth about $1356. And you can only get that back once you win the Incognito random selection lottery. Unstaking based on chance kind of sucks, especially when you need that 1750.
I think, like the warning button in the PDex for low liquidity trades, a change to the unstaking mechanism needs to be a top priority–especially as more and more nodes go online, further decreasing the odds of earning (and therefore unstaking).
