The fact that this exchange looks good doesn't mean it's a safe place to be. because once you have an issue which you need the help of their support team over, then you may get stranded for months if not years.
Pros
if you are not using this exchange then you are missing out a big deal. Many friends of mine who i recommended to use this exchange have shown satisfaction at the service rendered by Poloniex. I love the speed at which withdrawal executes on this exchange.
Cons
The main issue of poloniex is support team is not active. the major project like Revain, Neo, Tron and other projects are not listed on poloniex. sometimes UI of poloniex is crashed or taking so much load.
