I read on some forums and facebook groups that mining bitcoin is not profitable now so they convert to altcoins mining. But it still depends on your specs, how much it costs you to build it and your monthly utility bills. Still profitable but I think mining altcoins is more profitable now.
I also read that too in a site, still uncertain if we should agree to that or disagree. But I think that whoever wants to mine bitcoin can do so if they have calculated or do an estimate of their profit after all expenses on electricity or software. We may be neglecting bitcoin mining now, when the price pumps up watch how most people will rush back to it. Bitcoin mining can't be quited so soon.
