I bought some gold recently and as I held it in my hand I thought to myself "How do I REALLY know this hasn't been counterfeited, or filled with tungsten or something like that?"

Bitcoin cannot be counterfeited.  That has intrinsic value.
Bitcoin can be stored somewhere secure AND somewhere that is convenient to access.  That has intrinsic value.
Bitcoin can be easily divided down to make a smaller transaction.  That has intrinsic value.

One day I hope I can throw away all my gold because bitcoin made it worthless.
