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.
You should change the title to something better because you already said that it won't delete or replace any currency. All of the replies share the same answer which is NO the efficiency of Bitcoin won't remove/delete/replace any kind of monetary system. I think everyone here knows Bitcoin is one of the best crypto since you've posted this in a bitcoin forum.
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 !
People don't understand Bitcoin because there's a lack of interest and many of them don't care at all. Most of what is being reported about Bitcoin are bad news which ruins Bitcoin's reputation.
