I like the small local exchanges that is why I am occasionally using CoinCasso which is located in CEE region. They are attracting users via promotions (I got some of their native token which can be used for lowering trading fees). They have few users and not so many trading pairs but still you can find some crypto worth to trade here. They have fiat gateway and you can even trade for PLN (you can also trade for EUR).
The fees are fine.
They have interesting feature long short which is an app in which you are guessing in 60 sec btc options, you can choose up or down and win 80% above your deposit.
They have some interesting cooperation which bring some unique tokens to the platform such as Loot tokens.
Overall it is a good experience to try something different but do no expect it to be your main exchange.
