Is it better to save money in bank or invest it online, in real estate or maybe gold?
Both investing and saving is important in my point of view. Saving is useful in handling unexpected situation,like emergency fund. whereas Investing is a great source to make extra money. You just need to set a goal if long term or short term.
Depends on how risky those investments are. If you're in low a risk investment (i.e. low risk shares) then you can afford to differentiate less as it's less likely that they'll fall rapidly in value. Nonetheless, it's still always a good idea to invest in different financial instruments as well as different businesses - having an investment in the housing market will insulate you from a falling share market for example.
