those farming the 15 new perp dexes forget some of the history of these older ones. $dydx and $GMX were 2 former leaders that had decent market share before HyperLiquid.
This space is extremely competitive and even though HL is going to stay #1, their overall market share is prob down from here.
HL and Lighter are #1/#2; I think that the overall returns are going to be solidly weaker with each new dex that comes out. It could be extended, ostium, variational, edgeX and sooo many others...hard to say.
