I think holding of gold is better because it has physical appearance and can be used as luxurious accessory to the body and gold now is near to being rare. Unlike BTC it has to physical appearance and only can be seen in Internet which is only useful for business and gaining profit no more else. Holding gold is better for it gains value and can be used as a beautiful accessory.
Why do you not say about virtual gold, currency for forex, stock, gold market? You can not bring Gold to trading on worldwide because it needs you spend many money to transfer global. But while you use money to deposit in a trusted market and this market gives you virtual gold, this gold also has same value with real Gold, you can use that Gold to buy/sell anywhere, it is very comfortable. Finally, trading gold or Bitcoin on worldwide all depend on internet
