the 2 main factors are the price of the hardware and the price of you electric.
i enjoy free power as student. or is better to invest in cloud from cex.io.
if you have free power then get a good price on some mining hardware. hell pick a few Antminer S1's and put them to work for $40 its hard to beat. take a while to earn your money back and make profit but with free power its much quicker then cloud mining.
Cex.io is good but you wont earn much from it and return is about a year on it these days and some days you can LOOSE money on it
like i said if you have free power then your one of the few that will find it hard to loose money if you get a good deal on some used hardware then your sorted
i will try to find some mining equipment if the price is right. thank you for your reply.
