i think it better to save our money than invest that, cause we invest our money there some risk as like we lost our money
If there is no risk then the income will not be good, good ROI associates risk. So if you don't want risk then you cannot invest or do business that you know others will be holding your money and make it grow for you. Saving is good if you know that you have an income coming from your jobs and don't want to try to earn on risky ways.
The thing there is we all want to make money but we do not want to invest, I think there is not science on that kind of thinking. If we will remain saving our money we might lose the chance to enjoy our life more because in bitcoin world there are a lot of opportunities that could fit on our interest.
