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.
exactly and it depends on the location, if your in a tropical country its hard to invest on mining because you will need a cool place to avoid overheat, it will cost a lot and you need a big investment overtime if you will mine and you have a good location i recommend you to mine altcoins its easier to mine rather than bitcoin. It is also much easier to buy while the value is cheap and sell when the value hits your desired profit for 10% to 30% or even higher it depends on you.
