where do you live, because you say it's banned? if it is like venezuela or other countyr like bangladesh it's better to avoid, you may end in jail there
usually besides this you need to look at bitmain, they sell the antminer s7 for cheap and with your electricity it would be profitable an you would reach roi, in a reasonable time frame
I've heard that Bitcoin mining was banned in some countries but I still can't imagine someone really goes to jail for it. Were there such cases actually? I hope not, but unfortunately I may be wrong.
