Instant verification, instant deposit (no fees), can buy and sell instantly. Trading fee is 0.1% on market which use for big coins like BTC/ETH. 1% for instant buy/sell, which is ok considering so many coins offered. Easy compared to sending to binance and have to take so long.
Security seem very good, feel safe to keep my coins here. Have been trying a lot of exchanges, and this is my favorite so far.
Plus say are most popular in AUS, have a lot of people on facebook/twitter. If price goes up very high I feel safe that they will give me my money when I withdraw. Some of the small ones, scared they cannot give everyone money when they try at the same time. Just my opinion better to be safer then sorry.
