What happened to this project? It looks like dev has not been active for a long time. Look at the price today on coinmarketcap (https://coinmarketcap.com/currencies/auroracoin/) its price is very cheap just only $1,3 right now.
I am not for sure, but remember that AUR coin has another offical thread on this forum. You can search by google engine to find it. I hope it helps you out.
