user19228: If you own a small amount of Bitcoin (say,$10) does one have to "invest" it somewhere for it's value to change or will the $10 fluctuate by just sitting in one's wallet and one can see the value fluctuate by checking the wallet from time to time?

user20709: Bitcoin value is analogous to gold or foreign currencies. If you buy a gold bar with US dollars and wait a year, and if the value of gold increases during that time, then when you sell that gold bar, you will get more US dollars.
The interesting thing about bitcoin is that is was discovered suddenly and the demand increased because of the internet, so the value increased faster than most other assets we are familiar with.

user20702: Whether it fluctuates or not depends on how you express value. If you happen to be one of them American folks, who use dollars to express value, then a fixed amount of money in other currencies (such as euros or bitcoins) will fluctuate.
But similarly, a $10 dollar bill will fluctuate in value, if you express value in euros or bitcoins (basically, that is if you live anywhere on the planet except the US).
It's all a matter of perspective.
