It doesn't really work in this case. If you look through the periodic table, there is essentially nothing but Gold and Silver that is unreactive and plentiful enough to be stored to keep it's value.
Bitcoin is great but can't be guaranteed to keep it's value like Gold and Silver, it could legitimately be replaced by something better and antiquated in no time, reducing it's value to zero.

Bitcoin at this stage is a good investment, but it will live or die by being used for trading.  I try to use it whenever I get the chance, I encourage others to do the same.
