thanks for your answer.
do you mine alone or in a pool?

1st lesson in trading business.... DONT PANIK!
2nd lesson dont invest money that you cant afford to lose.

Is LTC mining still profitable?
Does one HD7850 make $?

I started with BTC Triplemining. With them the last 24hrs of shares you produce count.
I tested also Coinotron. I used the GUIminer srypt and they the speed and shares need some minutes to show up on the website.
However, i didnt took long to get a "reward" as they call it.
If you dont see a speed or a reward in your account after 24hrs then your setup is wrong.

edit: with Coinotron I tested LTC mining.

from your screenprints i see that you are mining with 25.7mh. That's to low to be profitable.

here are two links for you:

hardware comparison

nobody knows when the ASIC mining hardware will be ready. But then the difficult level will be pushed up so high that the CPU and GPU bitcoin mining will die.
All these GPU miners will flip to litecoin mining.

So my advise would be, stay away from mining, or buy a good GPU based rig and mine litecoins.
