If you have find a good investment, it's better to invest your money into it. It will give profits and your money will increase. If you pick save your money, your idle money will not increase.
Yup, if you find a good and refutable one..So far this days its hard to find an investment that will not run or will continue for years...The only investment I know that will give you a sure profit is when in the office there is a cooperative, you can invest your money there and you'll get a good ROI...Saving your money I think is good but it is better to invest it and earn more...

Finding potential investments that would run long time is difficult same as you said because we should be fully aware and do more research regarding on informations on a certain investment when you intend to put your money on. Cooperative was a good idea though because you could possibly get a good roi and it depends on how you gonna handle and manage it. Saving is good for long terms and emergencies.
Investing has never been easy in fact is way harder than just saving your money since you have the risk of losing money but the rewards are totally worth it.
Yes, I agree that investing is difficult especially if you don't save enough money to invest. Saving, on the other hand, is also hard, but it is not as hard as an investment because it is the preparation for investment. Then after you have saved enough, that is the time you can invest. It is when you do your research and queries on the company you are interested in investing. So yeah, harder to invest than to save money.
Yes I agree with investing is harder than saving and also saving is hard also especially if you are not into it. I mean if you have not been doing it before. I am having a hard time parting my salary before to put in a bank because of a bad habit in spending. They always say to save first before expenses.
I have read before that investing will give us more income or return compared to saving. It is because when you save, the interest is so low, there is a tax, and inflation. Unlike if you will invest the return would be bigger.
