Here is my view for Gold. If anyone contradicts, feel free to let me know.
I always feel Physical Gold is always better. Because.. today Govt said they cant give SGB anymore because as we brought SGB, govt should invested it in gold but they didnt, so govt facing losses for giving existing SGB's.
Tomorrow govt may say they cant give 4% interest on already given SGB's. Or they may say SGB's are not at all valid anymore and they can give only the principle amount to the investors and not the actual gold value.
And Govt may increase taxes / exit load on Gold ETF's / Gold Bees.
They may stop giving permissions to invest more into Gold mutual funds - This may stop inflows to Gold MF's and MF companies may exit from gold investment.
So always Physical Gold is better. I think you already might be investing a lot on other type of investments like stocks/MFs/NPS/ePFs etc and all are digital ones.
So atleast for Gold, let us go for Physical format to balance our portfolio
