Yes i can only dream of becoming rich with bitcoins because in real its not possible for me and for many others as well.Its not even possible for me to make a normal living with the bitcoins,but i am pretty happy whatever i earn with bitcoins,i will try to increase them a bit more with more work.
If you (also counts for other people) already know that you won't get rich, then even dreaming about it is pointless if you ask me.
Another note is that you shouldn't put your focus on making a living with Bitcoin as every bit you earn with Bitcoin should be seen as an extra/bonus.
Just keep earning your bits through whatever way, and treat it as a bonus reward. That's much better as it also gives you a better feeling since you then don't force yourself to do something.
