You have two options: mine or trade. By mining for Bitcoins, as long as the markets remain active you can basically make money for nothing. But the problem is, mining is such a tough gig now that it is hardly worth it. Turning your computer into a miner will likely make it noisy and heat up. It would likely take you a long time to even mine a single Bitcoin, by which time you probably would have spent more on electricity. However, if you have access to some serious computing power and you don't have to pay the bills, you could make some easy money here.
The more realistic way of making a million with Bitcoins is going to be trading them through the most prominent exchanges, such as Coinbase. Back in 2011, you could have bought Bitcoins for $10. Selling them at $1,000 today would have delivered a profit of $990 per Bitcoin. Basically you should have bought about 1,000 Bitcoins back when they were cheap. This would have cost you around $10,000 in 2011, making you a millionaire today.
