I see it on the road map. I also see you guys putting up all these stupid coins that have zero deposits being added and zero trades. I'm asking you to add SBC cause at least I have some to trade. I don't get adding zeit, gpu, and iCoin ones people have barely heard of (might all be awesome) and have _ZERO_ trade volume. Can you help me understand? Other then just the admins like those coins?
We have a list of coins that will get added to the main list. I believe Bill has setup a voting thread at:
https://bitcointalk.org/index.php?topic=497351.new#newPart of my responsibilities here is the wallet infrastructure and implementation. The reason for adding these newer coins is for me to test disposable wallet infrastructure. As part of our scaling out strategy, one thing I want to be prepared for is the ability to support new coins and have a manageable infrastructure that can be brought up and tore down quickly. This allows us to test new wallets without risking our current established wallets. You'll notice that both ZEIT and GPU aren't listed on the main trade bar on the left; that is the reason why.
For the more established coins, there is multi-tiered system that have higher availability and a higher cost of deployment and maintenance. I know this isn't a perfect answer, but that was my thinking when I convinced the team to do these two coins. I highly doubt you will see anymore adhoc additions going forward.
