Without the "trade" the coin does not derive any monetary value since it is not really used for anything else. So people that only stake needs to learn that staking by itself produces Zero Value monetarily.
It doesn't have to be just trade (not just coin to coin, usually currency can also be used to buy things), and also its just the value on these exchanges.
Doesn't mean in the future it won't have any other use and that other (types) of exchanges won't exist.
Cynicism, non-speculative thought, close mindedness leads only to loss of opportunities.
If you don't like the coin - what are you doing here?
I believe you are smarter than what you've just said.... unless you think I'm wrong.
