It's an interesting test to see if selling a home for an alternate cryptocurrency is viable. However, one home is not a strong sampling to determine if this will work. If a buyer should appear and wish to save money by using the alt-coin, then the value will increase as they will place big buys on the open market for DGC. If anyone already has the DGC from mining, then the value of DGC will not be affected as only buyers push the value up.

Many homes and products have been purchased indirectly from bitcoin, mainly from the conversion back to FIAT.
