The most rational solution is to have an investment in both gold and bitcoin. It is both profitable and safe. Do not keep all your eggs in one basket.
i agree that you said better to have both investment but why you said its safe?
i know both is profitable but bitcoin investment is not safe at all. its high risk so dont inform to newbie that its safe.
all people need to know the profit and lose in this trading. it can build the awareness and carefull in trading.
