Thanks for advise, Now I can see that LTC topic is more fresh than BTC. It's looks like buying gpu's to mine LTC is better investment to mine, in worst case You will have nice gaming equipment, or just sell it with little lose(didn't see to much of ASIC for LTC).In my country mining is not so popular so graphic cards looks cheap. I will try to buy some coins, but mining looks like fun, a lot of people just mining for hobby, but in some days it can be very value.
