I wanna invest in gold bars this year

I have a great idea. Since my kids received so many angpows this year, i'm thinking of gold investing. Cos as far as i know, price of gold only keeps going up each year. Have you been to a goldsmith's lately. I wanted to buy a Mickey Mouse pendant for both my boys but found that its ludicrously priced. I decided not to buy and went for lunch instead. So, anyone here invest in gold? Gee... i think i'm going to buy a few gold bars from Monex for longterm investment. I'm sure my boys will thank me in twenty to thirty years time.
