If you are saving in bitcoin you are basically invested.
Saving in BTC is literally saving as well because in term of security, saving in form of BTC is much better but due to the volatility then there is some issue with saving in form of BTC. Basically saving and investing is more about what you are using your money for. If it is not as capital to increase your money then it is a saving but if it is as a capital then it is considered as investment
investing money gives you a chance to increase it over a period of time!
Some people just want to save because it is not as risky as investing
Invest, price of stock is very low, this will go up in a couple of years. 
The future is covered with unsure things and BTC has more chances to be higher in a couple of years
Investing is extremely risky, as the chance of loss is high and it may be a big loss.
I could see that you are getting into delusion with this statement because not every investment is extremely risky and you would suffer a big loss from it. Some investment is actually stable enough and will hold good amount in some years i.e gold or real estate.
Judging from your words that investments are risky, I could see that you are generalizing all investment as the same type of those HYIP and the other ponzi things while in fact they are not the same
