Do a lot of research and you should be fine.
Even though this is such a short statement, I agree with it. People thinks that they can just ask someone "How can I make my bitcoins grow?" and then the guy would give them something and would teach them right away. It doesn't work like that. Most of us didn't start like that. We have the internet and the internet is full of information that we can use to make our bitcoins grow.
The bad side in here is that if the guy who's asking is your friend, and you told them to do research themselves, they'll think that you don't care about them enough to take the time to explain bitcoins and guide them. They don't understand. We don't have a ready-made PDF in our computer to send to someone just in case they're interested in bitcoins. Nobody has time for that.
Learn by yourself. Google is your best friend in this place. If you want to know something, then google it. Don't expect someone to guide you or anything because everyone's busy here.
