save it or invest it, if we keep it in the bank little by little it will be reduced but only a small part of the decrease. but if we invest it is very risky and there are two options will be lost money and will be a lot of money is abundant because of the investment returns. if we want to invest we must be able to learn first and must have a strong feeling before acting other than that must be expert predict the situation so that the results in accordance yanh desired ..
my advice is both equally good and better to keep the money in the bank and a percent of invested in to keep it from losing big and although fortunately only a little bit there is an additional or increased than not at all, it all depends on the policy that uses it and should be wise and consistent in making decisions.
