Even with Asics BTC is not profitable you can never breakeven the hardware costs. So the better option is to buy a GPU and mine alts.
which alt coins are you mining? i've tried my hand at ltc but my hardware wasn't quite up to spec... was only getting 12Kh/s cpu mining
CPU mining is obsolete now. You can't have any profit in any coin. I am mining with an AMD Radeon 7950 it produces 550kh/s. I mostly Mine PXC with it. But some times I mine a coin which hasn't yet hit an exchange to get more profit from it. Then I sell that coin and buy PXC with it. I am mining for long term.
what is you thoughts about mining in any system is this good profitable or just taking too much time I have some discussion with few friends and they all talking about this its now not too much profitable in any case so please tell what your thoughts about these all in general
As I told if you are mining for long term then any setup which can produce 550KH/s is good for a small start. You just need to keep an eye on new & latest Altcoins. Support what ever coin you think will be profitable in future and when you see the right time to sell it then do it. I have been in this game for over 3 months now. I have reached my hardware breakeven. To add more when I started it was not profitable then too. After reaching my breakeven I kept my coins because I choose the coin after a long research and I am now the part of the team. So I know whats coming for it.
Still I would suggest you to wait for at least a month do your homework and then make a decision. I will be here to help you guys out. One thing I think you guys need to know is this,

This is an article about BTC being regulated by governments. This means BTC can either get successful or banned. You guys need for this thing to be resolved. My personal thinking tells me that people will always tell you that many things are impossible in life but the fact is that they even don't know about it properly.
