I think everything depends on the ICO. Whether the project reaches its big target or not, if they achieve that, I believe that the coin price will be good if it has been registered on the exchange. they expect not to be fulfilled.
If a coin is really good it will gradually increase despite on wherever it's listed. Like what people believe that once it's listed in binance it will skyrocketed, yes some of it but not all so cut the crap and don't depend on listing.
But who decides the starting price of a token when appear in exchange? How COIN A in ICO is 10 cents on exchange is 20 cents and COIN B 20 cents in ICO on exchange 1 cent at starting price?
The starting price is only determine by the market however there are some ico that put a base price on the value to avoid getting dump. Otherwise, don't expect that the ico price will be the price in trading sites so don't speculate your profit early or you'll be dismay.
