To begin mining bitcoins, you'll need to acquire bitcoin mining hardware. Bitcoin mining with anything less will consume more in electricity than you are likely to earn. It's essential to mine bitcoins with the best bitcoin mining hardware built specifically for that purpose. So is it really a good idea to start mining?
If you have much money to buy mining equipment, I think It is a good idea, But It is very expensive. I personally like to buy and participate in bounty campaign.
