Not a chance. the bitcoin can fall at any moment! is not a safe investment. Is true could reach few hundred dollars, but is the risk of falling every time. Like just another Wall Street thing. 

Hello, thank you for reply. I tried some different mining calculators but I got some big ridiculous results. Well whatever. I had some other issues too. My computer crash every time I push the stop mining button. On the CPU everything is fine but on the GPU (nVidia GT610) is blocking every time. However I don't understand what is the real Mh/s rate. The software running on the computer shows a 10-12Mh/s rate, but on site I have like 0.5 Mh/s ....once in a while 1 share accepted, then I get few Bitcoins, then they start to drop till they reach 0. I don't really get it. However I don't know if is worth mining with my videocard, but I tried just to get some experience.
The temperatures on the GPU goes up to 70 Celsius degrees, and is full load on 98%, I ruin it for nothing. I want to try a dual video card setup, but still I'm not clear how efficient can you go. In my country the electricity is not so expensive,but also as everybody I have a target of bitcoins to make. Seems more easy to make money selling shovels (rigs) than using it.

I try to make a living using the internet. Different methods. Now I'm digging this Mining stuff and I like to learn new things. Is nice to keep up to date if possible with the things going around the internet.

Download the lastest ATI Drivers for your videocard. That's all brother!

Have a nice mining!

Hello everybody! I came across this mining thing and I decided to give a try. There are some few tutorials out there and I learned the basics. However I want to understand more about how this work.
I use mining.bitcoin.cz, the standard Bitcoin wallet downloaded on my computer, a mining proxy and that's all.
However my results are no good at all.
I have a poor video card, a nVidia GT610. I'm not a gamer, but I decided to give a try with my actual video card.
With the best setup I get like 10.2Mhash/s. I noticed this is very low compared to what other people can do.
I want to ask you all a question. How about if I get another ATI videocard? I was thinking to get a Sapphire ATI 7770, and later a sister for her because my motherboard is an Asus P8B75-V and has 2 pci-e slots 16x and it supports crossfire.
Can anybody estimate how much Mhash/s can I do with a single ATI Sapphire 7770? But with a crossfire made with ATI 7770?
Also I want to understand where my bitcoins goes? In the mining.bitcoin.cz account I have different fields in my account section: Estimated reward: with red.. and it goes up when I have a peer accepted, but soon it drops, unconfirmed rewards, and confirmed rewards.. always on 0! Can anyboy explain me how can I make bitcoins with this system?
Also can anybody estimate how many bitcoins can I make in a hour using a single ATI Sapphire 7770? But using a 2 ATI's 7770 in Crossfire mode? Thank you very much to everybody, and I hope to enjoy this wonderful community!
