The past week I saw this question asked a lot. Every time Bitcoin goes down in value a even a little bit, some people seem to panic and wonder if they should sell.
The more experienced people already know the answer: no, just hold on to it. Things will look up soon enough.
Anyway, I decided to make a little website about it:
