It is always better to invest your money. The money that you accumulate in your bank account depreciates in value every year. That is because more money is printed and the prices of things grow. that simply means there is more money in circulation and you have to pay more for the same thing every year. So investing is very good idea. People can't get super rich just by working hard and saving their money. their aren't enough time to work you way to riches. You need to make money work for you with wise investments and compound interest.
