Gold does not have the power of bitcoin.
1)What if you want to buy a yacht or house and you have 30 pounds of gold there in your home how can you buy the with that.If you went on the plane with the gold to go see and buy the yacht or house the government would steal or seize your 30 pounds of gold in the airport and the seller could not easily transfer the gold into cash even if you made it to him with the gold.
2)But with bitcoin you can travel with any amount of money and to buy the yacht or house you would just send a transfer of btc.The seller of the yacht sells his coins at a exchange and send the cash to his account.
Anyone who says gold is better than Bitcoin is retarded
