If our developers all programmers, let them create own exchange.
Let's say crossNYANexchange with the possibility of exchange of any coin to any other through cross course NYAN somehow ... for example I have a little EAC-coins, to me they are not interesting now and I would like to exchange them to some other coin (even not for example to NYAN)  - where can I do that now?
Everywhere I only saw the opportunity to do exchange with predetermined cross pairs. Why not make software that would enables to exchange "any to any" having analyzed all the possible chains of exchange, even if not possible to exchange one coins to another in a single step. (Sorry for my english ... was in a hurry)

This (creation of such exchange) could be the programmers-made promotional campaign
