The PerpDEX I've been trying lately has zero trading fees and is pretty user-friendly. The spreads are narrower than I expected, and the depth of liquidity is also more than adequate. However, I've noticed that recently, more platforms are advertising "zero fees" while actually making money off the spreads. It's important to look beyond the surface and really assess the actual costs. Especially for those who trade frequently, these differences can significantly impact your profits.
