No I don't think it's out of place to do so, GENX is already listed in TradeSatoshi, Escodex, SafeTrade, further listings would only create more awareness and possibly increase volume
Listing on more exchanges will increase volume.
More importantly, listing on big exchanges will increase volume for sure.
The team should send listing requests to big exchanges, and stay away from scam ones.
i suggest dev team to concentrate on adding features to the project first. if people can see the real use case of this coin, then the coin will naturally have more value as more people will buy it. that's the right time to enlist genx in more exchanges. if genx has no unique features or planned use case or applications, then the project is not different from other generic coins. Dev team has focus to put this coin towards POS usage, this is good one and hopefully will be realized in the near future.
