Asked few friends who tested dydx and all of them enjoyed it. I must give it a try, I'm sure that its worse than uniswap for my purpose but ... 1inch was worse too, I tested it and loved 1100$ that i received from airdrop 
Just tried Dydx. Minimum transaction is 1 ETH - well this should be mentioned during deposit not during making a transaction.
Long story short. Dydx is not for swaping coins its for magin/futures traders that don't bother to pay 11$ deposit, 11% withdrawal, slow transaction.
