I feel like you came to bitcoins with the wrong idea. Bitcoins are a decentralized digital currency, not a way to make money. Sure, if you're willing to put down a couple thousand dollars to build a mining box you could end up making some money. But the best way to make money with bitcoins these days is to sell goods and services, same as making money with dollars. The difference is that the bitcoins you receive aren't tied into an unsustainable economic model like dollars are.
