Thanks!
i have accounts of coinbene, kucoin, bitfinex, uex, huobi, binance, cryptopia. For everyday use i choise binance. Very low fees, sharp (when you place order its on market in the same second), has great mobile app and desktop app with great interface. Its also the best secured in my opinion. Binance even helps users with hacked accounts - they have whose system for that and already prevented 2 massive theft form their users account from stolen API keys - they also started a Secure Asset Fund for Users (SAFU). Starting from 2018/07/14, they will allocate 10% of all trading fees received into SAFU to offer protection to users and their funds in extreme cases..
Rest of them i use only if coin that i want to sell/buy is not listed on binance.
Acording to fees, sharpness, interface, sense of security i would rank them
1- binance
2- nothing
3- nothing
4- nothing
5- huobi
6- bitfinex
7- kucoin
8- cryptopia
9- coinbene
100- uex
I also use decentralized forkdelta for coins not listed on any centralized exchange (mostly from airdrops).
