Morgan Stanley say bitcoin mining only profitable above 8600 dollars. I'm not sure this is correct though, especially if future valuations come anywhere close to fruition.
If you have a free electricity and a low cost expenses mining is alaways good then.
but mining is very expensive and if you are just starting i will not advice it to you now.
good to go with others, just search more and you will find it.
No where in the world we can get electricity for free,if you got means then you are stealing it.But the prices vary from country to countries so if your country has cheap electricity and cooling climate condition then you can make good profits from mining.And bitcoin mining needs one time huge investment because it needs lot of hashpower to mine bitcoins.
