I'm not a big fan of putting a low volume coin on multiple exchanges, I think splitting the trading traffic when even one exchange has low volume has a negative effect on the coin. I get the idea of more exposure, but if someone was really interested in it they would be on the exchange with the most trading traffic anyway.
I never though about it that way. Of course an exchange with high volume would be outstanding but why do you believe having it on other exchanges that aren't as glamorous would have an negative impact?
