If any dev list their coin on those exchange you mentioned then don't blame us even when the price of that coin rally or pump. Anything that comes from a bad and shady exchange will be met with doubtful eyes. If you want a nice community with lot of trust around your coin, stay away from shady exchanges with fake trading volume.
What would those developers do who are not having any ICO for their coin and are doing everything on their own, they aren't able to pay such high listing fees for the top exchanges and that's the reason that they apply for those exchanges and when they get enough of the funds then they can apply for the bigger exchanges, but the big problem here is how to differentiate between those developers who are actually willing to work and make that token a success and those who are in it just for the sake of profits.
