What's cracking Crypto friends

Recently I started to trade every day a little. I do this on Livecoin.
The thing is I don't know if I also lose on fee charges when the differance beteen buying and selling is little.
On LiveCoin you always pay 0.18% (It was 0.2) fee on trade (buy or sell).
This burns your little profits. I'm not sure but sometimes I think I lose more than I gain because of this d@mn commission.
So I was wondering:- What's the best exchange to trade dailly?- On what exchange do you guys trade and why?- How to prevent the fee charges burning your profit when the difference is small between buying and selling?Thanks.

I know Poloniex is best exchange site for day trade because have most of volume in crypto market on the world's
Poloniex fee exchange: bid, ask first 0.15%/order; instant buy/sell with bid/ask available 0.25%/order
Bittrex, Kraken, Hitbtc are exchange site have good volume for trade after Poloniex in present, Poloniex have some issue withdraw in past few months
