Exchanges are clearly not the same. Binance is number #1 when it comes to trading volume and userbase so logically, having your coin listed there means that you'll have a lot of potential investors who didn't come across your ICO and that will most then likely result into a high increase in the price. This is not valid for Binance only but to other platforms with a high trading volume such as Okex, Huobi, HitBtc etc.
