Depends on your age. If you are young you should diversify your investments and consider some high risk investments. As you get older you should be more conservative with your investments and have lower risk.
That's a good point of view mate. When you are still young try to invest for a long term so that when you get older and retire you will have a good fortune in your hands in the future. You can also invest at the same time in bitcoins where you can invest in short or even long term.
