What product/service do you need to make more money (or make it simply easier)?

[artbart]

Traders,
what product or service does your trading strategy lack? Meaning, you guys are probably enthusiasts or day traders, OTC traders, arbitragers or else, but some of you have money-making strategies and processes, flows, etc. Basically, you know how to make money.

I'm not asking you to disclose your strategy/process/flow, I'm asking what do you need (to improve) and what kind of product or service is that? Basically, how could an exchange (crypto-to-fiat, KYC is a must, AML operations applied) help you to earn more?

Even little hints on lacking trading markets would help a lot (zrx/eur maybe?).
