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.There are some people who has become rich by bitcoins. well it depends on our skill, knowledge and the way we plan for the btc which will make you reach. but one thing in general is you cannot become rich by just earning from one income you have to make sure you have other plan backed up which will give you another source of income.
