Mixed feelings about dYdX
Used the platform for margin trading and lending, and execution speed was okay but I had a stuck withdrawal process that took a couple of days to resolve. The interface isn't very intuitive for newcomers which can be frustrating. On the upside, the fees are competitive compared to other DeFi platforms.
Unreliable withdrawal times
I really wanted to like dYdX since it offers great use options, but my last withdrawal took almost a week. The app also crashed twice during margin trades which sucked. I hope they fix these bugs soon because the concept is solid.
Decent platform but some issues
The trading options are solid and the decentralized aspect is a huge plus for me. However, I ran into a problem with order slippage during high volatility which cost me some profits. Customer support helped but it took longer than expected to get a clear answer.
Mixed experience with support
The trading features are impressive, especially the perpetual swaps with decent spreads. But I had a frustrating experience when verifying my identity; the KYC process got stuck for days and support was slow to respond. Once past that, trading was smooth though.
