Even if they move in similar directions sometimes, it does not prove anything of a correlation. Perhaps if the investment funds are flowing in, there is a portion that goes to gold at the same time there is also a portion that goes to Bitcoin. But whatever, gold and Bitcoin does not move each other, unless either one of them will fall. In that possibility, the investments might shift to the other.
Both are different things for me, the prices of both are increasing today but this does not make them relatable. The benefits that Bitcoin can give you in trading you cannot get that benefit from holding gold. It is a safe way for keeping your money but not relatable and better than Bitcoin. For better investment and big results go with Bitcoin for long term trading instead of Gold.
