Well for me Ill pick bitcoin because its easier to convert to real money and it is easier to store.
We know its easy to convert bitcoin but it needs internet.. unlike gold anytime you can convert it in money just go to friends use your gold as your collateral you have now money.. or you can sell it in pawnshop and ready to use the money.. they are good bitcoin and gold so for me i will go in 50/50
each of them have something special, and all of your statement is right.
we know bitcoin is the new technology, people can send dan receive money more simple than lastday, but we need internet connection.
we know too, gold is the oldest survive payment system, and we can use gold "without " internet connection.
for invest bitcoin have more chance to get Big profit but high risk too. and gold give you low risk and low chance to get profit too.
i think buy all of them with 30/30 is good option, then use 40 for invest at other place like property etc.
