It is right that we have already much exchange for trading. Although we have more and we need also more trusted and High volume exchange like Binance ,bittrex . I am saying we need more exchange because the more exchange we get the more product we can see by that exchange. And the more product will launch the more problem will be solved in the crypto world.

Anyway, we should also be aware of the new exchanges. Always try to investigate before using any new exchange because the crypto world is now full of scams. Mainly we should aware of all new things in crypto.
