Primary focus is on DGC and it should be, but ARG has some really great features for minimalistic coin. It is very stable, fast, almost no orphans. It is the far best minimalistic coin at the moment... It would be unwise to drop it.. It is no competition for DGC, because it is the different kind of coin...
Yeah DGC is my favourite alt coin, however ARG is very underpriced at the moment and will be around for the long term given what Baritus has planned for it.
