As my friend's experience shows, it's more profitable to buy bitcoin rather to mine it. There are better ideas for investment, even outside the cryptoworld (which is now highly unstable and risky) 
Mining may not be profitable in countries where the electricity costs per unit is high, then adding equipment, space etc may be very expensive and in between if btc values fall then you would end up in heavy losses. So better to invest in coins and balance your portfolio.
