It depends on how you are mining. If you are mining and selling the coin on a day to day basis it's not good right now. You need to be mining with the assumption of what the .00135 BTC will be worth in the future or else your numbers will be screwed up. There is a real possibility that btc will be 25k-50k sometime this year. If you can mine now and sell later I think you will be good. Yes it could also go down but there is no reward without risk. I feel like a lot of people want to mine because they think it is a guaranteed way to make money and they just sell their profits daily because they don't want to take a risk.
