Leandro,
This seems like a pretty shady operation to me. It looks like you have registered the bitcoin.com.br domain for yourself, copied exactly the Portuguese version of bitcoin.org, added a bunch of doubleclick/adbrite/adsense advertising code (which I can't really see what it's doing because I use AdBlock), and then
added that crappy javascript CPU miner code from
http://api.bitp.it without informing us or your visitors that we're helping mine Bitcoins for you.
I actually passed your link off to a few Brazilian friends before I realized what it was doing. (They complained that it crashed their browser.)
Do you really think that you are going to get enough visitors to this page to earn anything mining Bitcoins with crappy javascript mining code on crappy Brazilian CPUs? You should have probably taken whatever it cost you to register that domain name and invested it in a ATI GPU (or just bought a few BTCs on the open market) .. I'm sure you would have come out ahead.
I don't think this is the best reflection on Bitcoin in Brazil and I hope that the people involved in the Bitcoin project shut you down for doing this.
