Do you mean physical gold coins with a bitcoin paper wallet inside them ? I guess this is a good thing if it means people are more willing to diversify into gold as well as bitcoin. In a decade or so it will be interesting to see if the gold is worth more then the code's original contents.
So far bitcoin has been gold since those coins were first made, the gold bugs will say that in the end gold will be value that is highest as it is more durable.
My reckoning between the two, bitcoin is not something you should hold forever, its meant to be traded and made useful; where as a gold coin can be held from young age till you retire and serve a purpose in value
Bitcoin is the combination of both gold and currency. In bitcoin, like a gold you can inverse your dollars.If you want dollar means you can sell back the bitcoin .I.e,trade the bitcoin and get the double or triple of dollars you inverse in bitcoin. In gold also the value is some how raise .But in bitcoin ,the price is keeps on increasing.
