I know this is a very noobish question, but... Can i mine with a Dual Core 2.4ghz CPU laptop? I'm only using free bitcoin websites to earn bitcoins and then buy a good computer to invest in bitcoin mining. Also, sorry for my bad english, i'm brazilian hehe ._.
If we will focus on the question that if it's possible to mine with a dual core CPU, the answer is YES of course. It's just that it will take a decade or more to get your first 1btc thru your beloved CPU "laptop".
anyway he will get his laptop overheated and dead before he mine his first bitcoinya it is correct mining in todays time is very wrong decision, you can mine but it will be loss of electricity and it is true that your laptop will also be dead due to over heat. it is better that you can raise your rank and join a good signature campaign and earn by posting in this forum in other thread freely.
