Probably the time in which you could get rich overnight with bitcoin is over, right now is the time of steady profits, while that maybe not as exciting it can prove to be incredible profitable in the long run.
I think the key to getting rich in bitcoin is continuing to collect bitcoin from the income you get and store it on a regular basis, consistent with what you're doing, having collected many bitcoin, then sell your bitcoin and you'll get a wealth
While that is a way to do it, with the current price of bitcoin I think is difficult for most people to accumulate enough coins in order to make that dream a reality.
