I think to be on bitfinex it is ridiculous, considering bitfinex often have problems about bitcoin hack on their site, what it is possible to get also a lot of ICN were hacked 
Can you mentioned one of this big exchange that has not been hacker at least once, Poloniex, Bittrex, SHafeshift have all been hacked before. Listing on Bitfinex is better than Poloniex in my opinion because that is where the real Bitcoin volume is.
