You could look on it like an invetment but in my opinion it's not healty. I prefer to look at Bitcoin as my private bank, where i keep some of my savings in case of banking system collapse or my gov decide to take my money or other scenarios that can happend and there will be nothing i can do about. It's just reasonable to do so.

If you think about Bitcoin as investment you will check the price all the time and get nervous every time price stop droping 10%+ If you treat it as a bank where you store % of you weath, you don't care if price drops 10% on a single day.
