The more exchanges in the market mean we can choose what is the best for us to use. More choices for us to pick which one is the best and more easy to make some arbitrage with some exchanges..
Yes that's my purpose too for arbitrage my coin into more exchange with best price , this happen when my local exchange can't handle price to sell it. And I am happy when exchange can withdraw fund without sending any document for KYC, even Cryptocurrency don't need that like debit or credit card.
