We need exposure for success and high volume exchanges like bittrex and poloniex certainly helps.
My opinion is on the assumption that we already have a great dev team !
Yes we do. But how does exposure help them developing the software?
Exposure make more people aware of the coin, more people want to get a slice of it, the price goes up and it certainly brings more investors/developers/etc to the coin.And the existing devs also gets motivated as they see their work is recognised and rewarded by the public, which boost the productivity even further.
Fully agreed with both of you. Be patient and wait.
