Overall Poloniex is a very efficient and reliable exchange, maybe a little bit underrated. i love the low fees and the speed processing each transaction. the interface is really simple and nice, doesnt get stuck processing.
Pros
They support many currencies, their ongoing security, and the ease of use for the features they offer to users all around the world ensure that they will continue to be preferrred by users.
Cons
Unfortunately there are some cons: not enough trading pairs to choose for trading. Sometimes very big spread between other exchanges. Low volatility with some altcoins, easy to buy but hard to sell. Sometimes long timewating because of overlauded servers.
