You are right, if a person buys gold, he can make a lot of money in the next few years.And in my opinion, this is the only thing in the world that you can give at any time and at the same time you will get money.But this person can only do the work that has a lot of extra money It can be used as a side businessYes, as for me investing in gold can make a lot of profit, the reason why is that, for example, if someone buy a gold probably for 5000 this year, there is high tendency that the person can sell it for 100000 in the next 10years.
