Gold holders are more than bitcoin holders because of the trust that gold provides to the holder. Bitcoin needs to be accepted worldwide before it could take this position of gold.
Gold has thousands of years of history as a store of value. It's reasonable to expect gold to continue to be valued by people in the future, which is why it retains value. Bitcoin has a history of 7ish years. Between the two, what would you trust more? Things only have value that everyone expects to have value. It's a self-fulfilling prophecy; the things we value are only valuable because we value them. Right now, bitcoin can continue to rise on the expectation that people in the future will be willing to pay more than what it's worth now. If you didn't believe that, you wouldn't be buying at $5700. The problem is we don't know this isn't a bubble. Bubbles don't become apparent until they pop, just like ponzi schemes don't become apparent until they crash. This commodity (it's not a currency) with only a 7 year history could be a new normal, or it could be an unpopped bubble. With only 7 years of history, and much of that not even meaningful, I certainly am not putting money into an asset with this type of valuation. The risk here is unquantifiable.
