Gatra is as dead as Satoshi unfortunately.
About listing, there is also the NVO DEX project. It is still under early development stage, but it sounds very promising.
NVO will propose a plugin system, such that someone could simply write a plugin to allow RIC trading with other currencies, without asking for any listing.
Unfortunately, the project is delayed, and for some reason, the developers are very quiet, so people are in doubt, some even think it is a scam, although I personally think it is legit.
It looks like many great projects are started by shy people.
If a pool owner could integrate a built-in RIC/BTC exchange, this would be really neat too.
XpoolX supports multiple coins, so it should be easy to implement a small exchange between RIC, XMG, XMR, ZEC, and VRM too, just by adding the possibility to deposit and trade.
With a trade fee, this would also profit the pool owner.
If the owner reads me, would you consider this?
We need to break our Poloniex dependency. That so-called "wallet maintenance" is simply unacceptable.
Although gatra has not been around, he did post that he is working on Satoshi 0.14.1 for Riecoin quite some time ago. If he is in fact working on that implementation it would likely include all of the prerequisites for integration with barterDEX or other similar platforms, but I do not have high hopes for completion anytime soon as it appears he is very busy with flixxo at the current time.
I had considered making an exchange for RIC but unfortunately do not have the time for such an endeavour. Maybe xpoolx could chime in on this?
I think we should work on adding BIP65 support for barterDEX, hopefully gatra can help merge the changes if someone can start on it.
Lastly, there are some exchanges that may want to add RIC, i have no doubt on some of the smaller exchanges RIC trades would make a large portion of overall volume for them.
