Looking at the PrepDex market along this line of thought, it's easy to understand why dydx, GMX, and Helix haven't achieved the scale of Hyperliquid. To put it bluntly, decentralization isn't the primary concern; liquidity and wealth creation are.
If DEXs can rival CEXs in liquidity, like Hyperliquiquit, users will be more motivated to migrate to DEXs. Otherwise, no matter how superior the technology or how sleek the product, no one will invest in them.
