It seems you are very rich to invest in Gold so I will advice you to invest in Both. One is a physical asset and the other is a digital asset and both of them have great potential in the long run. Thye shouldn't be neglected as long as the money is available to invest in them. If you just have the money to invest in one of them makes you want to know which one you will be investing in because I won't advice you to take opinions from others. It is your investment and you alone will be responsible if anything goes wrong. The consequences will be yours to bear. Check your financial strength and know the one you are willing to keep for long.
