It depends on electricity. How optimized your rig(s) is, what you are mining, etc.
Also that hardware holds value. You will always be able to sell a video card. How much, well that depends. Any card I bought for x dollars I can turn around and sell it for the probably same today.
I am looking for cards. I hope lots say mining isn't worth it and we see an influx of cards on ebay and I buy them up
Mining is also a great way to anonymously get money into the system. Without added fees of pulling cash out of your bank account. I take my earnings and further trade them.
Also mining is pretty exciting. Perhaps you could get into some smaller / better pools. Or solo mine a coin that maybe you get once every 2-3 days and see how your luck goes
If you are mining on ethermine / flypool, they are mining 1000 blocks a second and there is no fun in that. Or if you are mining to pull the cash out right away, not worth the trouble I think. Save your BTC. Sure it may dip more, but it will go back up.
