Who decided the pairing, the coin, or cryptsy? or was it a collaboration and if so how so?
I was glad to see EMC2 on the list.
I have no idea who actually decided the pairings -- the announcement was a complete surprise to me.
However, based on a few news articles and a
response from BitJohn, it looks like this is the first step of a staged roll out for Cryptsy and that they are planning to become a full Ripple gateway. If this is true, it makes sense that they support so many trading pairs against XRP, because Cryptsy could eventually issue balances for each of those coins within Ripple itself.
That is the point where it gets really interesting because Ripple's decentralized exchange and pathfinding will let Cryptsy users either trade their Cryptsy balances against any other liquid asset in the Ripple network (via
auto bridging), pay with their altcoin anywhere bitcoin is accepted (via the
bitcoin bridge) or pay with their altcoin anywhere Visa is accepted (via a
Shift Payments card).
It is also possible that Cryptsy is setting up XRP crosses with most of the coins on their existing trading platform and waiting to see which ones develop volume. Then, when they start issuing balances on Ripple, they could only support the ones that already have volume. That is sheer speculation, but it makes sense from a support perspective.
