getting rich should never be the first motive. and the times to get rich with bitcoin are over. you have to start small and from there you have to work your way up. if you have done that, then you can focus on your next targets. but never expect unrealistic things to happen. that is the basic rule.
If you buy more bitcoins you will be easily be rich in bitcoin in the future..
