i am new at bitcoin mining, like a week ago hear about it. is cloud mining profitable? i have checked pbmining.com and hashprofit.com it's like within 5~6month people can get the money whatever they invested. and isn't much better than house mining? like they will do all the work? only question is how legit are they. coz if they run like this way people would be rich super fast. yearly 100% profit  ???

Cloud mining is a lose-lose situation for getting a return on your investment. There's a reason why cloud mining companies don't but a return calculator on their site.  You aren't even mining, you're just investing in their infrastructure for a partial dividend. The control what's mined, when you're paid, and you have no control other than giving them more money.

I wish people would just use their money to buy coins instead of giving it away to these semi-scammers. At this point in time you will be better of 99% of the time buying coins instead of investing in any form of mining, and maybe the coin value will start going up if more people did this  8)

Today you give them $1000 and buy a 5 year contract.  5 weeks from now their website disappears and you have 4 years 47 weeks of contract left.  Good luck with that.

Unless you can be certain there is a real company with real hardware and a real location they can be operating a ponzi and you wouldn't know.

so is it good idea mining from home? or it's a bad business? say i want to make 2 bit coing/m what kind of rig i should need? should i use my own pc or better to buy machine which is made only for mining?

You'll need dedicated mining hardware.  You also need to realize that to maintain a steady income, you must constantly add hashing power to your mining operation to deal with the difficulty adjustments.

You need to do a ton more research.

Depends on what your goal is.  If you want to make a profit then yes it is a bad idea since pretty much every home user will lose by mining (at least presently).  If you find mining more enjoyable than the money you're losing then it's worth it.

As johnnybravo0311 stated above you can't maintain a continuous 2 bitcoin income rate - you would need to add hardware every difficulty decrease (or conceivably remove hardware should the difficulty fall - that hasn't happened in 1.5 years).
