you can't mine with your PC like before anymore, you will need ASIC miners which if you ask me is not worth the investment, also you will end up paying a big electric bill.

p.s we don't need a topic for "ask question here" .
it is better if people search their questions in the forum first and if they don't find it "start a new topic" about it. this way others can see the question and answer it and also others who might have the same question can find their answers easier this way .
