some new and great coins can not be traded there because of the limitations of the resources (servers, disks, memory etc).
Is hardware/bandwidth/etc limitations really that great? I don't imagine a trade pair that doesn't have much volume would actually take up that many resources. If I am wrong, please explain!
It would be nice if there was a market health stat. Im not sure exactly which variables would be factored in but i'm sure something could be made that helps indicate which markets are actually trading and sustainable.
