Ok so I downloaded the bitcoin program and started it up. And the program started downloading thousands of blocks. I haven't clicked anything or signed up anywhere, I have tried and i think succeeded in finding my address, no sure though. Now it is still busy downloading blocks. On the overview screen it shows wallet out of sync. How do I sync this or does this happen once the blocks are done? How do I make/get/mine bitcoins, any websites that can be recommended? Do I have to add my own money to get started?
