my investment
This is one of the big problems I see. Lots of people think Bitcoin is some kind of "investment scheme", it's not. Would you "invest" your money by depositing it into PayPal? Bitcoin is a replacement for PayPal. Use it just like you would PayPal. If you need to accept or send a payment to/from someone over the internet, then use bitcoin. Buying bitcoins to speculate on the value is gambling, not investing.
It's not more strange than to "invest" in USD or EUR. When the Euro fell last spring I actually invested some. Sooner or later they will fix their economy and I'll sell.
Anything can be an investment. Even stamps or toys. But no investment is safe of course, otherwise everyone would do it.
