I recently read
[/] "An Order-of-Magnitude Estimate of the Relative Sustainability of the Bitcoin Network" , from Hass McCook .
In this book , he made a detailed study about estimating
the durability and cost of the Bitcoin network. He compares
Bitcoin against the gold industry, the banking system and the production of physical currency.
And , Bitcoin is by far the
most energy efficient monetary system we have ever made !
Here are some numbers:
Banking system: 23340 million GJ (energy consumed) + 390 million T of CO²
Bitcoin mining: 3.6 million GJ (energy consumed) + 0.6 million T CO².

I don't know yours opinions about that , but I'm really excited , I want that erveryone know that !

I know guys that it's really hard to delete these systems , and maybe not possible , I just think Bitcoin is the best system , and I just want to share my opinion , to touch a lot of people , and sensibilize them , it's important.
Nowadays , a lot of people are still thinking that Bitcoin is a scam , " a bubble" , they don't know the technology , they speak before learning , they don't understand and don't want to understand.
And I want to educate these people, it's my mission , and I sware iI will succeed : my goal is that people understand what is the potential of Bitcoin !
