>If you have gold, silver, platinum, you will always have at least some demand from the industry. Even if the majority of the current market price is due to speculation you still have an actual need for the metal. That's not the case for bitcoin. You could have the market losing faith tomorrow and it's done, your coins have zero value.

Is there a difference between investing in gold (30% "real" value, 70% "speculated" value) and investing 30% in copper (100% "real" value) plus 70% in bitcoin (100% "speculated" value)?
