Do you go to the market to buy your daily necessities with your gold?  Do you use gold to make your payments?

Ever since paper money was taken off the gold standard and used as the sole medium of exchange, people started holding gold only as an investment.

If you wants to trade it like as usual you need to change the view of Fiat currency on people and we need to go back to Gold Standard only then we can freely trade and consider Bitcoin as a digital currency for trade each other not holding it and pump it to sell. It's us who decide what will bitcoin be.

Although bitcoin is tradeable, you can use it as a payment currency. Right now maybe not a lot of country of system accept this method but day by day people's are thriving to accept this method.
