I was using this turkish exchange because they were giving a lot of free crypto for easy social tasks. I was able to get some free top 100 tokens (for example CRO).
The main focus of the exchange is TRY and there is little room for other traders using different fiat currency. The liquidity and userbase is not so high and there is sometimes problem to trade and it is mainly true for small altcoins. I have traded their native token FLX which promised good use cases but I am feeling now it is not going to achieve them. It is not a good idea to be in the turkish exchange right now. On the other hand they have quite low fees. The customer center is not helpful, I have had some technical issues with signing and it still persists. If you have different origin than Turkey you can look for anything else.
