If you bought bitcoin before some days when it was extremely cheap then you can see the profit these days to sell all of them.
Or you can hold even more longer maybe bitcoin price will increase much more.
The hardest part is you dont know when the right time to buy or sell is, since we dont have any idea what will happens in future.Or you can hold even more longer maybe bitcoin price will increase much more.

As a newbie, actually the first section you should visit is this https://bitcointalk.org/index.php?board=39.0 Good luck 
The right time to buy is when the price crashed and when you see that the bitcoin price has dropped for example -14%(red) this is the best time. And wait for weeks or days depends and sell it when the price increase for example +5%(green)
