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
Yes at this stage we should try to collect as many coins as possible as we never know what price bitcoin will touch in future and if it skyrockets then even descent amount of coins can make us rich in future.
