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 !
Bitcoin was introduced in 2008 and that time it was considered as a alien technology and no one was ready to believe it and those who believed bitcoin that time are now bitcoin billionaires and now the bitcoin is most successful and the most powerful crypto currency and the most investing investment of all and due to its huge potential, it has been used by millions of people for investment and due to its numerous of advantages, it will replace all the Fiat currencies available in the market.
