Will Rise be on any major exchanges right after ICO? Polo perhaps?

bittrex surely, polo who knows...but I don't think
Poloniex doesn't add coins easily... you need to be pretty special to be added on Poloniex. There are still a lot of older coins from the small Poloniex exchange start, but lately, almost nothing was added and if they add something then it are huge coins like LISK, DAO... even Waves didn't manage to be added. So Poloniex, nope, unless they pay 10 BTC to Poloniex and even then...
