I prefer bitcoin because holding your gold wont make you rich what i mean is there is no changes in price and gold nowadays is having a low value
But bitcoin i think this would be higher than a platinum
You are right it will not make high money for you and you will not be rich with bitcoin. it is good to use both high profit and for this you will have to manage time. If you are holding gold in you safe at home I am sure it will be risky and any one can easily break your lock of safe and will take your gold but if you are using bitcoin it is not risky because having bitcoin in wallet is good and no one will be able to use it without your permission.
