btw guys, which mining program can you suggest me to mine? I have AMD mobile graphics and have tried CGMiner and BFGMiner but I wasn't successful mining through them.
If you're trying to make money, I would not recommend mining with your current hardware. If your electricity costs are low enough and you don't care about your hardware, then it might still be profitable, but I would keep expectations low.
The most recent versions of CGMiner no longer support GPU mining.
If you're just starting out with mining, I would try NiceHash. It's not the best for profitability, but you'll get an idea of how much you can expect to make. (If you use NiceHash, I would just take a look at what algorithms your system appears to perform well on, then join a pool to mine a coin that uses that algorithm. If you only have that one system and keep using NiceHash, it'll take a very long time for you to reach the minimum BTC payout threshold, not to mention the burden of fees...)
