Yobit - A supposedly russian exchange that is not registered anywhere so they can say f*** you, we can't process your withdrawal request after a month.
Hitbtc - You can't trade small amount and they might keep asking for a hell lot of documents and even origin of your funds before they process your withdrawal if amount involved is large.
I would suggest you to only use binance which have enough liquidity and you don't have to pass KYC to trade small amount.
You are very right to your definition of this two exchanges. They are both not good at trading experiences, many traders also asking that these atleast two exchanges will revise their protocols so that small time traders can avail their services. I have an experiences on being scammed by Yobit recently , that's why I am picky of choosing a trading platform/s where I can trade my coins/tokens.
