If the aim is to make money, gold investment is not one that can make money overnight or after 5 to 10 years.

There's a lot of Gold platform available, but be careful of the business model:
1) Hidden cost / charges which is a great turnoff if you are a small-time investor. Off course which business would highlight their cons. They would be more happy to highlight their pros than cons. For cons, usually a consumer will find out the other way round.
2) Authentication of product. Not many are willing to buyback the gold sold to you. Maybe Pawn shop will take ? That's also if your Gold is genuine
3) Support services given. Is it really fast and in a level acceptable or will it fade as times goes by.

Always read carefully from the website and also read the feedback of current and past consumers and do the judgement.
