Ok, so the only way is exchanging money? How adding money to the network was done before there was enough bitcoins?

I don't understand. There should be a way to create new bitcoins (increasing the amount of existing bitcoins, that is how it gains its value), because creating bitcoins is allowed until 2140. After that, there will be only exchanging.

I was looking information about buying Bitcoins, and I found out Bitcoins can be bought only using sites which offer this kind of service. How can I buy Bitcoins without using those sites? There should be another method, based on the P2P network of Bitcoin. Besides, those sites offering exchange of money, which means replacing my money with existing Bitcoins, and not creating new Bitcoins.

For renting your resources (CPU, GPU, Electricity) to the network? If I had a powerful computer, I would have been a miner too.

By the way, here's why I thought fees are not always needed:

Ok, and who is getting this money?

Wait, I thought the fees are required only when delivering a large block.

Why do sites prefer to deliever a group of transactions and pay a fee and not to transfer it one by one?

I know, but usually after less than half a hour it has confirmation. Meanwhile, I received some more transaction which are already got confirmations.

I've got 0.00002 BTC from CoinAd.com a few hours ago, but it's still unconfirmed, according to Blockchain.info. What can I do? What happens if it stays unconfirmed?

LOL

Please explain me how [the HELL] a person got ~1487 BTC? :S

I'm sure it wasn't from selling something. I prefer getting paid from online tasks (not gambling!), unfortunately they don't pay much. I'm guessing the best pay to earn is to start a website which offers users to get paid for viewing ads, putting ads on their sites for BTCs, or any game which gives you BTCs (like the ORB and similar sites).

I know where to get a CMS for creating a site like the ORB, maybe after getting some BTCs I'll try running one myself. I wonder how much is it cost to run such a website.

I recently started to earn money online, but as I see it, those sites let you earn a very low amount of money (duplicates of 0.01 mBTC), but I've seen in Blockchain.info's history that people are earning huge amounts of money, from tens of BTCs to even 500BTC. How do they do it? Provably not using mining, otherwise they won't be using Blockchain.info, or they are only using it to transfer money anonymously? Of course that in most of the transactions you will see only an address, and not who owns it, besides a few sites that Blockchain.info knows their address, so these records doesn't really help me, also because there is no way to contact the owner of the address.
