i think Bitcoin is only profitable if done at large scales. you must get expensive mining equipment and of course it consumes a lot of electricity monthly. Also its usually much more cost effective to buy Bitcoins with this money instead of using it to buy mining equipment.
In my opinion, it is better to buy bitcoin with its current price in the market than mining because it was an obvious that bitcoin's value will still increase as the time pass by. It is still up to your decisions and we are just here to give you some advice. For me, mining is costly because you have to consider the electricity that you will consume.
