This is really an interesting question, I like it. Actually, I also had the intention to get rich from Bitcoin, first to know Bitcoin, I did not have this idea but since I realized the true value of Bitcoin I changed my mind. I have found every way to earn more Bitcoin, I am involved in investment projects but not effective. Then I switched to trading, trading altcoin types and working on forums. I find this way quite effective, I have earned more Bitcoin. However, the dream of getting rich is still quite distant because everything takes time, I need to act and do more 
It is possible but it will be hard. The days in which you can easily double or even triple your Money with Bitcoin are now over. Right now it has a slow movement above 1000$ comparing it to its movement below 1000$. It is trying to tell us that if the demand does not increase it won't move up to our expectations. We can easily find other investments that are rapidly growing such as in the stock market.What do you mean when you say slow movement? Last November the price was a bit more over the $700 and two weeks ago about $1275. I don't know any other currency which presents such fluctuations. On the other side when someone has the dream to be rich with bitcoin depends the place he lives. There is big difference who is considered to be rich in Nigeria and who in Switzerland.
