Bank deposit will be secure your amount of money in the future and anytime once you want to get it you will get it for sure.
Gold and silver gives you high profit everyear and your income from them you can deposit it through bank.
Is gold really giving us big profits every year? because basically gold can't add to our wealth. but maintain our wealth from inflation. and also the interest profit from the bank is cut to the level of inflation, actually it is not so big. unless we are millionaires who invest in these instruments.
Even though you are a millionaire and you put your money in the banks for a safe deposit then it would still make no sense for you to put it there because your money will be eaten by the inflation since the interest of the banks are pretty much lower compare to the potential of gold. Gold is better than banks and it is a no brainer.
