An opal marketplace would probably be achievable - my only concern really would be demand. How many people that are into cryptocurrencies will also be interested in buying opals?
I like the idea of possibly backing the currency up with real opals though. I imagine they have a fairly stable value.
Yeah It might not be a main focus, just something people can use opal for if you'd like, because people always seem to ask "what can I use this for other than trading?" (even though they only ever use crypto for trading it seems). I like the idea of possibly backing the currency up with real opals though. I imagine they have a fairly stable value.
Might be handy when the holidays come round.
"Look Mom I got you some precious Opals"

Perhaps just a limited supply market that is only open for a short window??
