Actually, we don't need as many exchanges as existing, but it's competitive market, and the best exchanges absorb the biggest audience. It's hard to say that the abundance of exchanges is bad, because if there were only 1 or a few exchanges, they could create a monopoly with very harsh fees and other conditions for users. So I'm rather for a variety of exchanges operating under different terms & conditions than a monopoly of a few exchanges. However, we still have a few big leaders that can affect the whole market, and that is not very good.
