These days, I see everyone talking about re-staking and shared security again.

Basically, it's splitting the same "trust" and selling it multiple times, the returns seem to stack, but so do the risks—it's just that many people don't want to look at that layer.
When something really goes wrong, it's not about "earning a little less," but when the penalty mechanism triggers, you might get wiped out entirely, including principal and interest... (I know I might be a bit pessimistic, but please don't pretend it's not a big deal)

The collapse points of blockchain games also make me think: rampant inflation, studios turning the economy into a spiral as soon as they come in, and finally, when the coin price drops, everything crashes.
If re-staking only focuses on "more layers of returns" without considering the underlying security assumptions, client updates, malicious windows, etc., the added layers might just be an illusion.
Anyway, what I care more about now is: who is managing the keys, how are confiscations enforced, whether there's a stop-loss switch for bugs, and the returns are... more of a matter of luck.
