So as for now at mid-2017, in comparison with the early days of crypto currency mining, it seems to be a none profitable or has a littile margen of profet. let's see why; and what i am trying to say, may vary, depending on what kind of country or economy you are in right now.
but lets see : if you need somthing you go and buy it, of course if you can afford it, regardless of the reason. but here you don't need to mine, so you can get out and and get a mining rig. you probably wanna do that as an investment, so first you gonna be risking your investment as there are 2 factos that might not be predictable, which they are; the dificulty level of the mining, and the future price of the coin you may mine.
so you can afford to invest more than a 1000$, i might suggest that you inest in the share or coin exchange market and with bit of luck you might double that if did your homework right, and incase you can invest more than then 10,000$ !! go and open a convinient store or a grosory store, that might be better and perhaps you can live of it.
so what i am trying to say if you do not get your investment back in 40 days, or if you can not live of your investment from the first month? chances are, you are loosing.
now let's go into the fun part, if you want to mine anyway, and if you are a nerd like me, you probably own a god rig, so you can use 50-75% of you computing power mining easy and worthless coins probably to get it much simpler you can go with www.minergate.com, as for now i recomend Bytecoin, as you may be able to collect 100 of them each 24-30 hours, just of the fun of it nothing more.
So if you are using your pc alot? and you may have couple of cores of your cpu doing nothing? you could through some mining work on them and colect some worthless coins that some day may fluctuate and become your lotery ticket.
to give some idea here is my mining work from 4 days ago in adition to the withrawals:
