For me bitcoin,because here you can earn a lot of money even in short time just focus and workhard while in gold you still waiting a long time for high value.
In this case too, bitcoin take the advantage. There are so many people who dont have such money to invest in gold as gold cant be bought in some portion. There is little investment in gold but you couldnt find anything better for you.
But bitcoins are amazing in here too. There are fantastic chances for people to buy as much as they want and as they can. Prices get high and they will earn.
