NILI, I deal with artists all the time (you have seen my projects). If you're an artist, deal in ART!!! People don't care a rat's ass about coins unless they can mine or profit on them. People want something they can hold and look at! Create ART!! Sell ART!! You can give someone 1000 Coke Coins, if they can't do something with them they are useless!!
I'd be very interested in seeing some of those projects and hearing about the circles you're in. Here's a bit of what I do...
