I think Bitcoin needs a currency system reform.
Really? Do you think that will happen any time soon? You would be better off if you stopped wasting your time trying to change Bitcoin, and created a coin of your own. BrasilCoin perhaps? I can see it now!

I'm sure you helped many people lives telling them what they have to do with their time.

Just like you suggesting the Bitcoin developers need to make changes to the Bitcoin software and hard fork the network.
Who is going to write the code, you?
Obviously you have absolutely no idea how ridiculous your suggestion is, what it involves, and why it will never happen. This thread is a complete waste of everyone's time, including yours. I was just pointing that out, hopefully by sacrificing a few minutes of my time, I can prevent many others from wasting time on this thread. Time that would be better spent on something more productive.
