You should do what makes you happy. Are you still into Bitcoin for the fun hobby aspect? Or has it changed for the money? Or is it one or the other? Nobody can really answer this question, it really just depends what you want out of the whole experience
I got into it originally for the promise of riches but I love the hobby aspect as well. I think maybe I will sell off 3 of the ASIC miners when they arrive and mine with the others. I am getting anxious for them to get here. I have never spent so much money on anything in my life. Not to mention it was nearly a year ago!
