Some years ago mining was a great idea. Now with the power shortage causing unannounced blackouts especially in the summer (in summers there is a 2 to 4 hour blackout almost every day), the government is very hard on mining and punishes it severely (unless you have connections in the government). There is a special cash reward for reporting miners to authorities. Still, Some people are doing it, especially if you can do it in a school or a mosque, it's almost free. (Public places get free utilities) Miners get discovered in such places a lot.
