It is better to save money with most of the money and invest a part of it saving money will be something which is sure but investing can have negative results. So I'd pick a little bit of both.
In what part did saving has negative results? I don't think that saving is going to have negative results at all because I know it has positive results.
Because you are the one who is going to benefit it if you are going to be a good saver of money. Just like a kid they are treating saving as investment.
Because they are going to benefit it in the future or if there is an emergency happening.
Well believe it or not, saving can have negative interest rates, for example there are some banks, that instead of giving you positive interest rates have negative interest rates, the banks are charging you money for the privilege of holding your hard earned money!
