Why don't do both. That's an awesome thing when hobby and making money are the same thing.
Most hobbies suppose spending and least time, but in many cases money too, but in our case, although we spend time here, we have the opportunity not to only gain knowledge but to earn some money too. And this is not so typical.
But you are aware that when you acquire the knowledge first, it will be easier for you to make money, with the information we acquire here is what will give us the insight of making money, I'm just capitalising to whom that introduced people here, because I believe if the information they processed to their brothers and lovely ones is to go and make money in bitcointalk, without signatures campaign many people will be offline in bitcointalk, let their interest first be in having the knowledge of bitcoin at hand not to immediately earn money, that's my point
