of course bitcoin has defeated the gold in the business market. The rate of generation rate of money of the bitcoin is high then gold in a specified time. The user of the bitcoin are so many time of the gold. Gold user are limited while bitcoin user are unlimited and growing day by day.
For me i think there is no comparision of both. Although gold stability will be better to compare real products you see in daily life but bitcoin is best stock in the world according to me because price value of it. We need to check the ounce of gold rare with bitcoin. It's value is more than a ounce of gold now. I suggest you to invest on btc to see the better profit than gold.
